Lungfish (Scientific name is Salamanderfish) is a freshwater fish famous for its ability to live on land. They can live for months without swimming around in the water, even years. The reason is that, with normal fish, the bubble is the part that helps the fish keep balance when swimming. But in lungfish, the bubbles develop into lungs to take oxygen directly from the air. Their fins also gradually change into swimmers. In the presence of water, lungfish swim normally, eating fish and small crustaceans. When the dry season comes, these places run out of water, lungfish will burrow into the mud by eating mud with their mouths and then excreting through the gills. When they reach a sufficient depth, they secrete mucus through their mouths to harden the mud, forming a cocoon around it. The mouth of the fish is the only part that is exposed to the air. Electric eel (electric eel) is a dangerous “water monster” in the Amazon River. They have a special ability, which is to generate electric current from cells called electrocyten located on the side. This current can reach 600 volts, enough to knock down a horse. Many electric shocks from this creature can cause heart attack or respiratory failure in humans. When attacked by electric eels, normal people will be stunned and drowned. Electric eels locate their prey by generating 10 volts of electricity before stunning them and killing them with stronger currents. Clownfish (clownfish) has an orange body with three white stripes. Most of them live in shallow waters in the Indian Ocean, the Red Sea and the western Pacific Ocean. According to the Mother Nature Network, clownfish are hermaphrodites with the ability to reproduce like both males and females. An interesting fact is that up to the right size and condition, clownfish will have the ability to change sex. Specifically, in a school, only the two largest clownfish are responsible for the reproductive function, they are the only couple in the school. If the dominant female dies, the male leader will change sex and become a breeding female. The second largest male will quickly develop into an adult male to pair with a new female. Siamese fish is one of the popular fish in Thailand. Possessing a variety of colors and beautiful round fins, Siamese fish are loved and kept as pets by many people. Besides the colorful appearance, Thai Siamese Siamese fish is also impressed by its unique ability to change color. The color of this fish’s body will change according to the environment, even if their mood is not good. Siamese fish is also known as an intelligent fish. They can be taught to swim with their fingers or push the ball into gold. They are also known to be aggressive and are often used in “fish fights”. Barrel eye fish (Scientific name is Macropinna Microstoma) is a strange fish with tubular eyes, located on the inside of the head and protected by a transparent shield filled with liquid. Their eyes are sensitive to light and contain a green pigment, which helps the barreleye fish to survive in the deep sea when hunting and hiding from predators. These eyes are even rotatable, allowing them to look straight ahead or look up to see everything overhead. The barreleye fish lives in the deep seas of temperate and tropical regions of the Atlantic, Pacific and Indian Oceans. They spend most of the day maintaining a fixed position in the water thanks to their large flat fins. Devil face fish Verrucosa , also known as coral fighting fish, are commonly found in coral reefs under Australian waters. Their bodies can be up to 50 cm long and possess 13 venomous spines on their backs. The venom of the devilfish can cause heart failure if humans accidentally touch its venomous spines. In addition, the devil face fish also has a large body, many fins on the back and rough red-brown patchy skin like rocks. Taking advantage of this advantage, they often hide in coral reefs to hunt. After identifying its prey, it launches a bite in just 0.015 seconds to swallow the opponent.

Their venom is made up of a mixture called peptide conus. Each of them will have a unique venom formula. More than 50,000 conus peptides have been discovered, they are all neurotoxins and no vertebrate species on our planet possesses this form of venom. Marbled Cone snail possesses an extremely splendid appearance but is considered the most venomous snail species on the planet. They are purely carnivores and predators, feeding mainly on sea worms, small fish, mollusks and even other cone snails. It can release venom at any time in its life, and this species is always ready to wipe out all living things around it. A cone snail, like most snails, moves slowly. However, its attack is extremely quick and powerful. They use a sophisticated detection system to find their prey. Snails eat fish, sea worms or other snails if food sources are scarce. Their secret to hunting doesn’t lie in movement speed, instead they hunt using venom and develop an extremely efficient venom system. Because of their slow movement speed, cone snails often hunt by “holding a tree waiting for a rabbit”, which will lie in the sand at the bottom of the water, only revealing its long tubular mouth and tentacles in the sand. Once it detects prey such as a small fish or something passing by, it will use strong muscle contractions to shoot the tongue connected with the venom gland from its long tubular mouth at lightning speed and “close the gap”. nail” into the body, injecting poison into the prey. This venom will paralyze prey within seconds and die instantly. To prevent their prey from struggling, some species of snails have created a toxin that can reduce pain and anesthetize the prey’s nerves, making the prey feel no pain and slowly die without even realizing it. know. When the prey is fixed and no longer struggling, the conch will withdraw the “hook” (toothed tongue), pulling the paralyzed prey into the mouth. One study estimated that this species alone caused 36 deaths. Divers are afraid to face the Marbled Cone snail. They are very beautiful, just like other normal snail shells, but when hit, they are very fast and even with diving gloves, the snail’s proboscis can still penetrate. A few microliters of the toxin in a snail’s saliva is strong enough to kill at least 10 people. Once the poison enters your system, you may not feel symptoms for several minutes or days. Although the bite is not painful, you may feel numbness or tingling. However, then your whole body may shake, your eyes will go blurry, and your breathing may stop after just a few hours. However, the function of this extremely toxic substance is only for self-defense and to catch prey, but they never actively attack humans. Up to now, about 30 people have died from accidental contact with the marbled cone’s spit. The life of the snail shell collector will end when the sharp hook of this snail pierces the person. The most powerful poison called neurotoxin will temporarily paralyze your nerves. After that, the respiratory organs will close, making it difficult for you to breathe and this can be the worst part. Symptoms of a snail sting include local pain, swelling, numbness, tingling, and vomiting. Symptoms may appear immediately or slowly over several days. In severe cases, muscle paralysis, vision changes and respiratory failure can lead to death. The various neurotoxins contained in cone snails are called cono toxins. In addition to being toxic to humans, in this venom mixture there are many beneficial substances, which can work accurately and quickly on the human nervous system without causing side effects. Therefore, this snail can also open up a new medical future for humans. For example, cono peptides have the potential to prevent spasticity caused by spinal cord injury and may help diagnose and treat small cell lung cancer. Conotoxins can immediately generate nerve signals that reduce heart rate or turn off pain receptors. Ziconotide isolated from it is used as an analgesic. It is said to be 1000 times more effective than morphine and not addictive. Conotoxin ACV1, isolated from Victoria cone cone in Australia, is more effective than morphine and Ziconotide, has a longer analgesic effect and is convenient to use without side effects. It has been shown to be very effective in the treatment of post-operative and neurological conditions, and even accelerates the recovery of nerve damage, and is expected to be developed as a treatment for anxiety. , Parkinson’s disease, muscle tension and hypertension.

A spokesperson for Sharkbanz meanwhile confirmed Mark Zuckerberg purchased two Sharkbanz devices from the company’s website. Photo: Instagram The Sharkbanz bracelet for $84 claims to be able to help the wearer prevent accidents from shark attacks by emitting a special electric current. This current can make sharks more likely to sense electromagnetic fields as they search for prey. Sharkbanz’s products have actually been used by quite a few people, including former US President Barack Obama. Photo: Sharkbanz Although very famous, many experts have expressed skepticism about this product line in the past. World-renowned diver Erich Ritter told DW in 2017 that he did not believe Sharkbanz was effective. “These bracelets only protect people psychologically,” he said. “They don’t work at all.” Chris Lowe, director of the Shark Lab at California State University, says he’s never seen any data that suggests people should use a product like Sharkbanz. Even so, Sharkbanz and many 3rd parties confirm that sharks tend to stay away from ringed dummies in tests.

This species is extremely toxic, it prefers to hide in coral reefs, rocks and sandy seabeds from intertidal to intertidal zones in southeastern China and tropical seas. Their bodies contain more than 200 pharmacologically active substances and a single drop of venom can kill 20 adults. To date there have been at least 100 recorded deaths from the venom of this species and the actual number could be much higher. The creature we are talking about here is the Cone Snail, also known as the cone snail, is a marine gastropod mollusk, so far more than 70 species have been found along the coast. along the coast of China and there are more than 1,000 species discovered in the world. Their venom is made up of a mixture called peptide conus. Each of them will have a unique venom formula. More than 50,000 conus peptides have been discovered, they are all neurotoxins and no vertebrate species on our planet possesses this form of venom. The Cone Snail has a mostly cone-shaped appearance and the largest can be 23 cm long. They are purely carnivores and predators, feeding mainly on sea worms, small fish, mollusks and even other cone snails. It can release venom at any time in its life, and this species is always ready to wipe out all living things around it. But surely you will find it difficult to understand because in our impression, snails are very slow-moving mollusks, how can they hunt, especially fast-moving species like fish? In fact, the secret to their hunting is not in their movement speed, instead they hunt by using their venom and developing an extremely efficient venom system. All cone snails are masters of poisons, likened to the five poisons in the animal kingdom. They have a tongue pocket in their throat, which contains many hollow toothed tongues, which resemble spearheads and are made of hard chitin. Because of their slow movement speed, cone snails often hunt by “holding a tree and waiting for rabbits”, which will lie in the sand at the bottom of the water, only revealing their long tubular mouth and tentacles in the sand. Once it detects prey such as a small fish or something passing by, it will use strong muscle contractions to shoot the tongue connected with the venom gland from its long tubular mouth at lightning speed and “close the gap”. nail” into the body, injecting poison into the prey. This venom will paralyze prey within seconds and die instantly. To prevent their prey from struggling, some species of snails have created a toxin that can reduce pain and anesthetize the prey’s nerves, making the prey feel no pain and slowly die without even realizing it. know. When the prey is fixed and no longer struggling, the conch will withdraw the “hook” (toothed tongue), pulling the paralyzed prey into the mouth. It’s worth noting that even when it’s not during mealtimes, if it feels threatened, the conch shells will shoot out without hesitation. So if you see brightly colored and beautiful cones on the beach, don’t stress. It came out by accident. Pick it up, especially the larger cone snails. This behavior can kill you because the conch’s nose can pierce the skin, gloves or wetsuit. Especially among cone snails, there is a species called Gastridium geographus, also known as geographical cone snail, killer snail, they are known as one of the most poisonous snails in the world, and one of the most dangerous snails in the world. marine animals that are extremely toxic to humans. One study estimated that this species alone caused 36 deaths. Symptoms of a snail sting include local pain, swelling, numbness, tingling, and vomiting. Symptoms may appear immediately or slowly over several days. In severe cases, muscle paralysis, vision changes and respiratory failure can lead to death. The various neurotoxins contained in cone snails are called cono toxins.

Bald eagles prefer to live near large bodies of water such as lakes and oceans and in areas with a good supply of food to eat and trees to nest. They are found largely in North America including Canada, northern Mexico, Alaska and the United States. The bald eagle is a North American bird of prey that is one of the rulers of the North American skies. It is about 71 to 96 centimeters long, has a wingspan of 1.68 meters to 2.44 meters, and weighs between 3 and 6.3 kilograms. Those who like the bald eagle will surely be impressed by its wonderful appearance with its yellow eyes, beak, and feet; dark brown plumage and white head. This bird has a majestic and majestic appearance. Unlike other eagles that eat carrion, bald eagles have a very strong hunting ability, they fly in the air, run on land and can swim in water. Everything in its eyes can become prey of this bird. Records show that a bald eagle tried to grab a large brown bear by the nape of the neck, possibly because the opponent’s fur was too thick to “take action” so they had to give up. . Even the subterranean rulers of North America are seen as prey by them, which shows that they are extremely “big” birds and are considered to represent bravery. Therefore, the fact that the bald eagle can become the national banquet of the United States seems to be not difficult to speculate. However, things did not go so smoothly, because Benjamin Franklin, one of the founding members of the United States, considered it simply inappropriate to represent the image of the United States. Franklin believed that the choice of turkey as the national bird was preferable because they were hardy and strong, never surrendered without a fight, and represented the true American spirit. As for the bald eagle, Franklin once said in a letter that it has many bad qualities such as dishonesty and cowardice, even a species that likes to attack other small birds boldly. But it must be said that, although the bald eagle is brave and good at fighting, the selfishness and cruelty of this bird is undeniable. In a nest of young birds, the strongest will try their best to get food, which can cause their siblings to die from malnutrition; When food is scarce, the larger bird will even kill and eat other young birds directly in the nest. Not only that, bald eagles are also openly hostile to humans. They plunder the fisherman’s catch at sea, and on land kill herders’ lambs, even adult sheep. In 1983, the Wilson Gazette recorded a case in which a bald eagle killed a 60-kilogram pregnant sheep. The most unbelievable thing is that there are reports that this eagle even hunts children. Either way, in the past, people in the US have developed a hatred for this bird, and some local governments even offer rewards for hunting bald eagles. Along with the widespread use of the pesticide DDT in the last century, the eggshells of birds have become thinner and more fragile, as have habitat reductions, collisions with power lines, and other reasons. Elsewhere, the number of bald eagles has plummeted. In the 1950s, only 412 of the 48 states of the continental United States remained, of which Alaska killed about 70,000 bald eagles in the first 12 years of the 20th century. After a successful pairing, the bald eagle couple will choose a tall and sturdy tree, they will frame the tree underneath and outside with branches, and then spread thick weeds and other animal feathers to make a nest. . When they have free time, they will do nothing but look at their nest. This nesting behavior lasts for the rest of their lives (about 20 – 30 years), they will constantly repair and as a result their nests get bigger and heavier – becoming the largest bird’s nest on the planet , with an average diameter of about 2.5 meters to 4 meters. Especially with the nests weighing up to 1 ton, it is definitely an extremely luxurious residence among birds. The largest bald eagle nest found to date is near the city of St. Pittsburgh, Florida, 2.9m wide, 6.1m deep and weighs more than 2.7 tons, and obviously it has been included in the Guinness Book of World Records. Of course, not all bald eagle nests are centuries-old and highly durable homes. Due to inappropriate site selection, many nests are often destroyed by storms in less than 5 years, or broken down by branches.

Illustration. White shark Jagged jaws and razor-sharp teeth make the great white shark the most feared killer in the ocean. Fast speed, sharp sense of smell makes it easy for great white sharks to defeat most aquatic creatures except giant whales. Sharks can smell blood from a great distance and quickly move to where their prey is injured. Photo:Discovery Adult great white sharks can be up to 4 m long and weigh about 1,100 kg. The great white shark becomes more aggressive when stimulated by the smell of blood, the researchers say. However, this animal does not intend to attack humans. Their poor eyesight causes them to mistake humans for seals or other animals. Great white sharks kill about 100 people every year. Photo:Discovery Killer whales Experts have had the opportunity to debate the hunting behavior of killer whales and come to the conclusion, this relatively complex way of hunting is not as rare as people think. “I’ve seen similar scenes with a number of different species of dolphins in oceans around the world, so I assume killer whales regularly ‘exercise’ complex hunting strategies with For example, with slower swimmers, such as seals and sea lions, killer whales prefer to use their tails to knock their prey out of the water, stunning it and then killing it. victim,” said an oceanographer from the US National Oceanic and Atmospheric Administration (NOAA). So how do killer whales possess superior hunting skills? How cruel are they? We will take a look at a few reasons why killer whales are known as the “cold-blooded” geniuses of the ocean. Saltwater crocodile The saltwater crocodile is the largest living crocodile and amphibian species on earth. They live in northern Australia, some countries in Southeast Asia or Africa. The habitat of this organism is saline rivers or lakes. Their body size can reach 6 m. The saltwater crocodile is the largest crocodile in the world and the largest living reptile in the world. Male saltwater crocodiles have been recorded at 23 feet (7 m) in length and 2,205 pounds (1,000 kg) in weight. Females are much smaller, measuring about 10 feet (3 m) long and weighing 330 pounds (150 kg). Adult saltwater crocodiles have an average of 66 teeth and the largest bite pressure of any animal in the world. The saltwater crocodile’s most feared weapon is a strong tail, large jaws and fast movement speed. They are known for their cunning for their unique hiding style and ability to approach their prey gently. This cheeky animal is ready to attack humans if they get the chance. Saltwater crocodiles kill between 600 and 800 people each year. Photo:Flick This is the largest reptile on the planet and every year they cause the death of more than 2,000 people. Lion Known as the “king of the jungle”, however, lions don’t actually live in the jungle. Instead, their main habitat is the grasslands and plains of Africa. This animal hides under the trees for about 20 hours a day to avoid the heat. They hunt in groups to increase their chances of killing their victims. The African lion is the largest animal of the cat family. Adult males can be from 3 to 3.3 m long. They use speed to chase their prey, pounce on their victim with their sharp claws before knocking it down with a fatal bite to the neck. Usually, the lion will try to separate the victim from the herd before surrounding and killing it. This animal kills about 800 people every year. The lion has many “gifted” physical traits that make it an excellent hunter in the wild. A lion’s vision, for example, is six times more sensitive to light than a human’s, giving it a significant advantage when hunting at night. Its claws can be easily retracted, stretched, and let out. In addition, they have the ability to reach speeds of up to 80 km/h in a very short time and jump as high as more than 10m. In addition to the symbolic roar, lions communicate with each other in the same ways that cats do: through whining and purring. Lions also rub their heads together as an act of bonding and spreading.” home scent.” This scent allows the lions to recognize the members of the pack when a dispute with an opponent occurs. Tiger Fish The tiger fish is the most bloodthirsty carnivore in the world. They breed and thrive on rivers in South America. The tiger fish’s most fearsome weapon is its sharp teeth, with more powerful bites than the T-rex tyrannosaurs if their jaws are as large as the most feared animals of prehistoric times. The teeth of the piranha are hard and have sharp, saw-like edges, making it easy for them to tear their prey. A school of tiger fish can tear large prey in minutes. The red-bellied tigerfish is the most ferocious of the piranhas. Scientists say tiger fish are attracted to the blood of shark-like prey. However, this animal is ready to attack prey hundreds of times larger than their body. There are also many cases of tiger fish attacking people in the wild.

Dolphins evolved from a terrestrial animal Dolphins evolved from a terrestrial animal Dolphins are mammals, closely related to whales, often living in the shallow seas of the continental shelf. Dolphins have the ability to understand simple human behavioral language. With their inherent magical ability, dolphins can understand and organize common objects into groups together. They understand both sounds and images, and even respond to images just like humans. Explaining this, scientists have confirmed that dolphins are the most intelligent animals in the world (while humans are only third in intelligence). Millions of years ago, the ancestor of the dolphin did not swim in the water as we know it today, but was a carnivore that lived entirely on land. However, about 50 million years ago, a mysterious event happened that forced them to adapt to the underwater environment, and gradually evolved into a mammal like today. Although they are considered extremely friendly animals, dolphins also have creepy habits, typically juggling their young out of the sea. This sounds like a very funny joke, but in reality, it is one of the ways adult males are killing their young so their mothers can return to mating. Dolphins can’t sleep for weeks at a time A recently published study has revealed the surprising ability of dolphins: They can stay awake for days or weeks at a time without sleep. So how can they survive without sleep? Dolphins possess a very special sleep mechanism, they can let half of their brain rest at a certain time while the other half is still awake – a process called “Unihemispheric sleep”. This special sleeping mechanism not only keeps dolphins from drowning, but also allows them to stay alert to any danger and even encourages brain development. Most dolphins don’t chew their food Dolphins do not chew food, or rather they cannot chew. Dolphin’s teeth are developed for the purpose of gripping prey. Sometimes they will shake or rub the food on the ocean floor to tear it into smaller pieces that are easier to swallow. One theory is that dolphins’ prey are mainly small fish, and they need to quickly grab the prey in their mouth before their meal can swim away. Skip the chewing process to make sure the prey can’t escape. Dolphins call each other by their own names, forming friendships through shared interests Researchers from the Universities of Bristol, Zurich and Western Australia have found that dolphins living in the Shark Bay area form friendships based on shared interests – in this case, the habit of using foam. sea ​​to hunt. This tool-using trait is found mainly in female dolphins, but by studying the behavior of a few expressed male dolphins, researchers have found a new discovery: The relationship of dolphins is formed through general tooling techniques. Dolphins have their own names and they will respond when called. Dolphins in each population possess their own “characteristic whistle”, just like a name, and other dolphins can use that distinctive whistle to get the attention of their mates. In fact, dolphins are also an extremely social species. The discovery opens up entirely new questions about how dolphins communicate and their “vocabulary,” and may reveal clues about the evolution of our own language skills. Dolphins use prey’s toxins as ‘addicts’ We know that puffer fish have strong toxins. Apparently dolphins know this too, but they use it for ‘high’ purposes. Usually, the puffer fish toxin is deadly. However, in small doses, it can act as a narcotic. The BBC once filmed a video in which dolphins gently play with a puffer fish for 20 to 30 minutes, then hang around and behave “weird”. Dolphins possess great “teamwork” ability A team of researchers from the University of Bristol recently discovered that male dolphins can work and work together as a team – an attribute previously thought to be unique to humans. Observing the behavior of male dolphins as they coordinated courtship with female pigs, the researchers saw cooperation rather than competitive behavior, which is particularly unusual in mate-finding in the animal kingdom.

The lizard has the ability to run on the super ‘top’ water The Central American lizard spends most of its time in trees or shrubs watching small insects or vertebrates pass close enough to grab it. But when it is threatened, it can plunge into the water and escape. The reason is that lizards have the ability to walk on water thanks to their skillful “rowing” rear legs with the support of a long tail. This talent for walking on water like doing a circus earned it the nickname “the lizard of Jesus.” Not only that, it is also capable of running on water at speeds of more than 11km / h and diving under water for 30 minutes. Hound’s sense of smell Under the sleeping hound’s sleepy eyes was his super sharp nose. This nose is 1 million times more audible than a human nose. That is why the police used to hunt for missing people or fugitives. A hound’s nose has more than 200 million olfactory cells, so it can store the odor and follow it for days despite the presence of other odors on its way to its target. Thanks to this super-sensitive sense of smell, the hounds become famous “experts” in solving cases in the world. The eagle’s eyesight All birds of prey have sharp eyes. And this is a powerful “weapon” to find food. But eagles have special eyesight above all else. According to calculations by scientists, eagles can see target details at least 8 times better than the most pure human eye. This is due to the fact that the sunshade in each eye blocks sunlight and has a high concentration of cone cells in the vision. As a result, it positioned its prey with incredible accuracy. The eagle can see a hare several kilometers away. That is why they are symbols of sharp eyesight. Find your way in the moonlight of the beetle Scientists have observed that beetles routinely move the dung ball that is many times larger than its body by “planting a banana tree” and using its hind legs to push the ball away. But further research they discovered that this insect also possesses a talent that has never been known in the animal kingdom: navigating paths by moonlight. It can move in a straight line despite obstacles they may encounter along the way. The beetle’s competition for food (other animal droppings) is fierce, so as soon as a colony forms a dung ball, it tries to hide this dung ball to do ” dry wages ”later. The fastest way to escape from another stumbler is the straight path. The miracle is that this species can trace a straight path just thanks to the moonlight. It seems that the insect relied on a pattern created when moonlight interacts with molecules in the air (polarization) to move in a straight line. On days without moonlight, beetles tend to change directions, take a detour to keep them safe and have less trouble. The lion dance Thanks to its incredible power and speed, the leopard leopard is one of the most terrible predators on the planet. But the lion’s leopard high jump and long jump skills are admirable. His muscular hind legs and large claws are designed for a powerful jump. The lion leopard can jump up to 15 meters (50 feet) away and jump up to 6.6 meters, which is quite a big difference compared to humans. It is the advantage of this long jump and high jump skill that makes it easy to catch up with prey even after a long distance. Navigating with the sound of the bat Bats are animals that possess many unique things and have very interesting adaptations. Many species of bats often turn upside down to sleep and live on the blood of other animals. They are also the only flying mammals. But the most impressive feature of the bat is its ability to hunt with echolocation. Accordingly, the bats send high-frequency clicks as they fly, then they hear the oscillation from the echoes bounce back and that indicates the prey position is not far away. With this system, they can catch and eat about 1000 insects per night. The ability of sharks to receive electricity Sharks are one of the most successfully evolved animals on earth. Thanks to the diversity of adaptations, sharks have many advantages in the wild. One of these adaptations is the ability to receive electromagnetic waves, making the electrical impulses in the shark’s body extremely sharp. As the prey swims, this movement sends tiny electromagnetic signals through the water. Sharks receive these signals as the water travels through the jelly-filled pores of the head. Connected to the internal compost, signal reception allows the sharks to find prey quickly and they can kill the prey with great precision even in cloudy water. This hearing organ also makes it possible for sharks to detect the smell of prey blood, even a drop, from miles away. Swimming speed of squid and octopus Squid and octopus are the fastest invertebrates in the ocean. This is in part due to the body’s extraordinary ability to use jet boosts. When water flows into their outer cavity, it is held under pressure and the mouth closes. As the muscles of the wall contract and press, pressurize the full water back through the cartridge and allow it to run at a speed of 40 km / h. These cephalopods can also control the direction and speed of movement, allowing them to escape from a threat or to quickly advance to prey they want. The magic wings of hummingbirds Not only are the hummingbirds one of the most beautiful birds on earth, hummingbirds are also the most impressive flying birds. The joints between the upper and lower wings are located very close to the body so they are agile and have a surprisingly leveraging effect in the air. Hummingbirds flap their wings at a frightening speed-80 times per second. They are also the only birds capable of flying forwards, backwards, upwards and downwards. Hummingbirds can float in the air, which makes it easier for them to absorb nectar while in flight. The running speed of the leopard At a speed of 110 km / h, the leopard is the fastest running animal on the planet. This is thanks to the long limbs, small head, and slim body, the spines will curl and stretch with each stride, helping to push the body forward faster. Thanks to this movement that it has increased speed more than 30 km / h. But the surprising thing is that this species can not speed fast for more than 10-15 seconds, longer it will cause their body to overheat. This is also understandable because leopards mainly live in deserts and steppes where there is very little chance of hiding in the shade.

Turantula spider The turantula spider is one of the most terrifying animals on the planet, not only the giant spider, but also a predator so stealthily and so skillful that no tiny animal is hovering in its sights. chance of survival. Turantula’s hunting trick is patience. They waited for the unfortunate passerby and grabbed it without warning. Because of their size, which can be up to 12cm long with a stride of more than 70cm, Turantulas can quickly crush prey and crush them under giant pincers. Eventually they bathed the victim’s body in digestive juices and sipped this “delicious” liquid. 9. Mamba Snake Africa’s scariest animal must be the black Mamba, this giant poisonous snake that is present throughout the Southeast of the continent. Its name comes from the black skin inside the mouth, which is only exposed before it attacks. These snakes are usually passive but can be extremely aggressive when threatened. They tend to attack the victim repeatedly, secreting a mixture of neurotoxins and cardiotoxin. The probability of dying after the bite of a black Mamba snake is… 100%. However, this number has decreased thanks to the use of antidotes across the continent. 8. Fish Piranha Out of all the fish, the Piranha is possibly the most notorious. Seeing sharp teeth and strong jaw is enough to cause chills. Piranha is known as a fierce predator, living throughout the fresh water of South America. They feed in the early morning or twilight, hide in the water and wait for their little prey to pass. Then, without warning, they attack and devour their prey with unrivaled ferocity in the freshwater community. In some cases, they will hunt in groups for larger prey, including horses, rodents and even humans. 7. Gray wolf Most of the world’s top predators are completely alone, mainly relying on their courage to take down their prey. But with gray wolves, the success of the hunt depends on the cooperation of his fellow men. The characteristic attack of wolves is the chasing of many animals in the herd, causing prey to flee. A single prey is not only easy to defeat, but also safer than a prey in a resisting position. The dominant male will lead the hunt while its females follow closely behind. Once the prey falls to the ground, the flock will surround it and finish it off. 6. Komodo Dragon The largest of all the varanids, the Komodo dragon is a powerful reptile with a weight of up to about 136kg and a length of more than 3m. This animal ranked sixth in danger due to the speed, strength and stamina to knock down its prey twice its size. It also had a poisonous blow, and any survivors of the Komodo dragon’s attack would soon die from their wounds. Komodo hunts mostly in ambush, but they also run fast and swim well. Moreover, its incredible hunting ability is also combined with the ability to consume, in one meal it can eat the amount of food equal to half its body weight. 5. Crocodile There is nothing more threatening than a predator always hiding in the water, in disguise and in the environment, quietly observing the prey to plan a kill. Ranked No. 5 on the countdown list is a crocodile, a sneaky and extremely brutal predator. With extremely strong jaws and long sharp teeth, alligators hunt for many different species. Some species, like the Nile crocodile, can cut down very large prey like zebras or buffalo. Its offensive feature is to lie at the edge of the water where the animal comes to drink and then pull the unfortunate animal into the water to begin to bite when it has slices of meat for a meal. 4. Whale killer Like its name suggests, killer whales are deadly predators, combined with formidable skill and unparalleled physical strength. Killer whales have a number of ingenious techniques in their hunting weapons, which give them one of the most diverse rations of ocean predators. For example, they love to knock seals and penguins from floating ice and then catch them when they fall into the water. They also go to the beach to catch the sea bridge on the shore. Being a highly social animal, killer whales tend to live in groups of about ten to hunt together. They can even hunt white sharks! 3. American North American Bear The North American Bear, also known as the brown bear, is probably the most terrifying animal in North America. This mighty predator can stand about 2m tall and weigh more than 360kg. Its strong arms and hands can kill a person in just one click, and its strong jaws also allow it to eat everything it wants, including large mammals. Bears run fast and swim well. Facing this species in the wild would be a traumatic experience, the best response is to stand still and not run away at all. The speed of this species can reach more than 65km / h and your run can make it chase. 2. Lions Dubbed the lord of the rainforest, lions hunt even the largest prey like buffalo and wildebeest. The near-absolute success of these predators is due to a combination of skills. Lions live in groups and all members go hunting together. The young lions soon learned hunting skills through a game of fighting together, which also decided their proper role in the chase. The success rate of a lion’s hunt is only 1/5 but the hunting abilities are emphasized when we consider their prey – both large and resilient. . 1. White Shark Any animal that has unfortunately caught the white shark’s sights does not seem to have a chance of survival. The white shark occupies the top spot on the countdown list because of its outstanding hunting ability. With its elongated bodies and strong teeth, the white shark is a powerful species: swim fast and this nimble ocean athlete can bounce out of the water to tip his prey. The white shark also has several rows of sharp jagged edges, each of which is replaced immediately after being lost. In fact, a shark can have more than 50,000 teeth in its lifetime. The white shark usually starts its attack with a fatal blow, then waits for the victim to weaken from the wound before enjoying it – this makes it possible to enjoy the meal safely.

The extinct prehistoric mammoth was believed to be prehistoric human prey. A controversial new study found that the first humans were large predators who took down prey with skilled hunting skills. In a new research paper, the scientists argue that humans and close relatives have been adept hunters from a very early age, starting at least 2 million years ago. Miki Ben-Dor and Ran Barkai, researchers at Tel Aviv University in Israel, and Raphael Sirtoli, a PhD student at Minho University in Portugal. “Until now, efforts to recreate the Stone Age human diet have been based mainly on comparison with 20th century hunter-gatherer societies,” says Ben-Dor. Of course, this comparison is lame, because 2 million years ago, hunter-gatherer societies could hunt and consume elephants and other large animals, while hunter-gatherers today. It can’t be like that. The whole ecosystem has changed, and the conditions cannot be compared. ” Scary evidence Fossil evidence from earliest human ancestors is scarce. But based on archaeological evidence, Ben-Dor said, it was clear that Homo sapiens and their close relatives ate anything that was edible. But how much of their diet consists of plants versus animals is the bottom line. Many animals that are considered omnivores actually have the diet in one way or another. Chimpanzees, for example, are technically omnivores, but meat makes up only about 6% of their diet. Dogs and wolves are predominantly carnivorous but sometimes also nibble on grain, leading to a debate over whether they should be classified as omnivores or predators. According to Ben-Dor, ancient humans Homo habilis ate meat at least 2.6 million years ago. Another primitive human species, Homo erectus, appeared to be an avid carnivore 1.8 million years ago; Their teeth and intestines shrank compared to their previous ancestors, adapted to digest meat instead of plants, and it used stone tools capable of grinding meat. Ben-Dor and Barkai argue in their paper, published in the American Journal of Physical Anthropology, that meat is not just a reward for these humans and the early Homo sapiens. Instead, the authors believe, large animals weighing more than 1,000 kg, such as elephants, hippos and rhinos … make up the bulk of the human diet. The elephants 500,000 years ago could weigh 12 tons, compared with 4 to 6 tons today. Eat a lot of meat, human brain evolution? According to the researchers, these animals can eat fatty meat, which is very suitable to feed the energy-hungry human brain. The authors argued in another recent article that hunting large prey could be the driving force behind human brain evolution. However, the idea is controversial, and researchers disagree on how huge amounts of meat would be useful to hunter-gatherers in the days before refrigeration, as well as about ancient humans skilled in taking down prey that other predators like lions, struggled to defeat. “There are some archaeologists who say, they hunted elephants once, but it’s like a once in a lifetime hunt; that’s what grandparents often tell their children,” John said. “There are people who say that elephant meat can last a long time without preserving, but it’s part of their routine,” said Hawks, a paleontologist at the University of Wisconsin-Madison. important to them. ‘” Ben-Dor and his colleagues wrote in their article that eating large, fatty animals would be a benefit to humankind at the earliest, because losing so many calories on a hunting trip – instead of repeatedly trying to stalk smaller prey. Humans exhibit this high-fat adaptation, researchers say. Archeologically speaking, it was difficult to classify humans and their relatives as carnivores before about 50,000 years ago. That’s because the only reliable biochemical way to distinguish an animal as the top predator or lower in the food chain is a method known as stable nitrogen isotope analysis, requires collagen testing for molecules that are taken orally into the body. Despite the limited evidence of humankind’s early evolution, the researchers say, much remains to be done to prove whether the human ancestor was indeed carnivores. This could include more research on the abundance of animals of different sizes during the Pleistocene, exploring genetic changes over time that could alter the digestibility of species. Different human feeds and comparison of prey size trends over time.

Dolphins evolved from a species of terrestrial animal Dolphins evolved from a species of terrestrial animal Dolphins are mammals, closely related to whales, often living in shallow seas on the continental shelf. Dolphins have the ability to understand simple human behavioral language. With their inherent magical abilities, dolphins can understand and organize common objects into a group together. They understand both sounds and images, and even reflect images that are no different from people. Explaining this, scientists have confirmed that dolphins are the most intelligent animals in the world (while humans are only third in intelligence). Millions of years ago, the ancestors of dolphins did not swim underwater as we know them today, but were a predator that lived entirely on land. However, about 50 million years ago, a mysterious event happened that forced them to adapt to the aquatic environment, and gradually evolved into a species of mammal today. Although considered an extremely friendly animal, dolphins also have creepy behaviors, typically juggling young animals out of the sea. It sounds like a very interesting joke, but in fact, it is one of the ways the adult male is killing the young so that their mother can return to mating. Dolphins may not sleep for many weeks A recently published study has shown a surprising ability of dolphins: Can stay awake for days or weeks continuously without sleep. So how can they survive without sleep? Dolphins have a very special sleep mechanism, they can give half of their brain a rest at a certain time when the other half is awake – a process called “Unihemispheric sleep”. This special sleep mechanism not only prevents dolphins from drowning, but also allows them to stay alert to any danger and even encourage brain development. Most dolphins do not chew their food Dolphins do not chew food, or rather they cannot. A dolphin’s teeth are developed for the purpose of gripping prey. Sometimes they will shake or rub food on the ocean floor to tear them into small pieces to make them easier to swallow. One theory is that dolphins’ prey is mainly small fish, and they need to quickly grab prey in their mouth before their meal can swim away. Skip the chewing process to make sure the prey doesn’t escape. Dolphins call each other by their own names, forming friendships through common interests Researchers from the Universities of Bristol, Zurich and Western Australia have found that dolphins living in the Shark Bay area form friendships based on shared interest – in this case, a habit of using foam. sea ​​for prey. This tool-use trait is found mainly in female dolphins, but by studying the behavior of a few male dolphins that exhibit expression, the researchers have found a new discovery: Dolphin’s are formed through general tooling techniques. Dolphins have a given name and they will respond when called. Dolphins in each population possess their own “signature whistling”, as a name and other dolphins can use that particular whistle to get their partner’s attention. In fact, dolphins are also an extremely social species. This finding opens up entirely new questions about dolphins’ communication levels and “vocabulary”, and may reveal clues about our own evolution of language skills. Dolphins use their prey toxins as “addictive substances”. We know that puffer fish are highly toxic. Obviously dolphins know this too, but they use it for “high”. Usually, the puffer fish toxin is lethal. However, in small doses, it can act as an addictive substance. The BBC has recorded a video in which dolphins gently play with a puffer fish for 20 to 30 minutes, then hang around without leaving and behave “strange”. Dolphins possess great “teamwork” ability A team of researchers from the University of Bristol recently discovered that male dolphins can work and work together as a team – an attribute previously thought to be unique to humans. Observing the behavior of male dolphins when they were coordinating flirting with female pigs, the researchers found cooperation rather than competitive behavior, which is especially unusual in finding a mate in the animal kingdom.

Most wild deer have no contact with humans. However, when threatened and during heat season, wild deer will probably attack you. In this case, calm down and slowly step back. If it shows signs of rushing to attack you, put an obstacle between you and the deer and run away or climb the tree. In case you can’t run away or can’t climb the tree, raise your arms and spread your jacket open for a creepier look. When attacked by a deer, protect your head and neck by curling up like the pose shown in the photo above. 2. When meeting a bear The bear does not usually come near noisy areas, but in case you happen to encounter a bear in the forest, absolutely do not scream or run away or climb into a tree, as the bear runs very fast and can break the tree. Easily. Make yourself look bigger by reaching up high, holding your backpack or jacket over your head, and slowly backing away. Once you are out of sight of the bear, you can run away quickly to safety. 3. When meeting a lion Mountain lions often attack prey from behind so never turn your back on it or run away because you definitely cannot run faster. You need to be more fierce than it is. You stand up straight and look him in the eye, hold your coat up high to look more scary. If necessary, throw whatever you have at it. If a mountain lion attacks, do not stand still but fight back. Try to hit its eyes, nose, and mouth and it may leave you alone. 4. When meeting wolves Wolves often live and move in groups. If you see a wolf it means others are probably also around. So, if your wolf sees a fairly large distance from you, slowly walk away in silence until you reach safety. However, if the distance between you and the wolf is very close and it has noticed you, here’s what you should do: – Slowly step back and don’t look away. – If the wolf comes close, scream as loudly as possible at its face and throw whatever is on it at it. Pay attention to your footsteps, for if you stumble, the wolf will pounce on you immediately. – In that case, attack with the most forceful force on its eyes and nose. When it sees you as a dangerous subject, it leaves. 5. When meeting a bison Keep your distance from the bison, as the bison will only attack when someone approaches it. Don’t be fooled by their slow, gentle appearance, bison can run three times faster than a human and have very strong vigor. If you accidentally approach a bison and see signs of wanting to attack you, give up. Find shelter behind trees, rocks, or any other object large enough to hide or climb on trees. Once you see that the bison has moved away, you can now move to safety. 6. When you meet the newspaper Never go near a leopard, especially cheetahs. Cheetahs may not be intimidating, but their mother will attack anything that gets close to her to protect her. If you come across a cheetah, stand still and do not make eye contact. If the leopard is about to attack, shout, wave, clap, or do anything to make you look more dangerous. 7. When meeting the hyena Instinctively, hyenas will chase anyone who runs away. So when you encounter a hyena, calm down and talk to it. If you have food, throw it to the hyena. Hyenas are lazy animals and if there is something to eat, it will most likely leave you alone. If it approaches you, surprise them by taking a few steps toward it and making loud noises, waving, clapping, trying to look as scary as possible. The hyena will think you are about to attack and it will most likely run away. 8. When meeting a wild boar The wild boar is extremely ferocious. So if you spot a wild boar in the distance, don’t stop to take a photo but leave the area immediately. If you are too close to the boar, do not run away, but do the following: – Keep calm and step back slowly. – If it comes towards you, climb the tree. Boars cannot climb so after being bored they will leave. – If it goes crazy and decides to get along with you and you can’t find any place to hide, fight it. A fight with a boar usually lasts only about a minute, you should fight until it leaves. Dieu Linh (According to Bright Side)
