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.

As it turns out, the act of killing a spider is not only a “bad omen” but also harms the home ecosystem. Even the cleanest houses have inhabited spiders. In the journal The Conversation, entomologist Matt Bertone and colleagues at North Carolina State University in the United States published a study of 50 homes in North Carolina and in each home they found spiders. According to Bertone, arachnids are important members of the inner human ecosystem. They are “omnivorous” predators and eat almost anything they catch: from a fly trapped in a window to a mosquito trying to suck human blood. Sometimes, the spiders eat their own kind. A house spider is watching for flies Many of the “victims” of spiders are potential vectors of disease. There is even a species of jumping spider in Africa that only likes to eat blood-sucking insects in the house. So when you kill a spider by hand, you accidentally “kill” a “soldier” to destroy the pathogen in your home. The indoor spiders are not the venomous monster spiders in Australia that we still see in newspapers. During his research, Bertone often found only common indoor spiders like Pholcidae * and the most harmless arthropods of the family Theridiidae **. Both of these spiders spread silk where they live. Spiders Pholcidae sometimes leave their webs to hunt and eat other spiders around. I don’t want to see this scene in my house at all, what about you guys? The truth is that most spiders are poisonous, but the venom of most of them is not strong enough to harm humans. The spider’s fangs are also often too weak to bite through the skin. Hollywood movies have sprinkled us in the head with spiders attacking us while we are off guard. However, in contrast to these movie “myths”, the spiders almost never crawl past a sleeping person. The act of snoring, puffing, or even ordinary human breathing is enough to scare away the vertebrates in the home. Furthermore, spiders are afraid of humans and always try to avoid us. We are far more dangerous to them than they are to us. Cases of spider bites are extremely rare. The scene is haunting for many people Although there are some highly toxic species like the Black Widow, they very rarely bite humans and even so, these bites rarely cause serious medical disorders. If you have phobia or simply don’t want to see spiders crawling around where you live, follow the scientists’ recommendations: instead of killing arthropods, catch them in one. box and drop off the road. The spiders themselves will find a new place and we do not have to carry the “killing” karma. *: Pholcidae are arachnids in the arachnid family of the suborder Araneomorphae. They have a body length of 2–10 mm and their legs can be up to 50 mm long. They can be found on every continent in the world except Antarctica. They weave a messy, irregular mesh. Spider webs are woven in wet and dark areas, in caves and under rocks, and abandoned animal caves. Do these spiders look familiar? Spider webs do not have cohesive properties, but their unusual insect trap structure makes it difficult for prey to escape. Spiders quickly cover their prey with spider webs and then inflict a poisonous bite to kill the prey. The prey can be eaten or stored immediately thereafter. **: Theridiidae is a family of arachnids of the order Araneae. This family has 109 genera, a total of 2295 species. The spider Theridiidae is usually reclusive, almost harmless and extremely gentle.

Professor Chris Buddle of the Department of Insect Ecology at McGill University, Canada pointed out that: “Out of nearly 40,000 species of spiders in the world, only about 10 can be dangerous to humans. Even venomous species are very unlikely to come into contact with humans, let alone attack us. ” Are spiders any color? It sounds strange, but spiders don’t really have blood. What they have is called “Hemolymph”. In fact, our blood is based on iron-containing hemoglobin molecules, so they are red. However, the blood of the spider is based on the protein called Hemocyanin derived from copper. This hemocyanin has a fairly clear color, but when exposed to oxygen it turns dark blue. Spiders cannot digest food in solid form They have to pump a liquid into their prey to soften their internal organs and tissues. After everything is softened completely, spiders can suck the contents inside to nourish their bodies. Spiders can control their blood pressure while on the move Spiders not only use muscles to move, but they also know how to combine blood pressure to walk or jump, depending on the species. Spiders contract muscles in the nipples and increase hemolymph pressure in the legs, which makes it easier for them to expand the area of ​​movement. This sudden increase in pressure also caused their legs to leap in different directions. Spiders have no vertebrae Spiders have no bones. They have only a set of sclera surrounding the organs and blood. This makes them classified as invertebrates or non-vertebrates. However, spiders are not the only species with sclera. Practically all insects and arachnids have that set of sclera. Having a set of sclera allows these organisms to grow more and periodically they need to “strip off” or replace their sheath. They can also re-develop the body in a short time. All invertebrates (even spiders) are very vulnerable before their sclera can harden. There is a species of spider that actually lives in the water There is a species of spider that is adapted to live in water, also known as the “Diving Bell” spider. Special soft hairs surround their bodies in the shape of air bubbles that provide oxygen in this particular habitat. Spiders are also a vegetarian Bagheera Kiplingi Spider (Kipling Spider) was discovered in the 1800s, their main food is acacia buds and plants. Sometimes this spider also eats larvae. It is also the only vegetarian spider in the world. Spiders will eat back their old spider silk When the silk loses its cohesion or becomes too dirty, the spiders often eat it and use nutrients from the old silk to create a new web. Do you see ? The spiders recycle them… in their own way. Antarctica has no spiders. Antarctica is inhabited by spiders. These are simply places where the climate is so extremely cold that they cannot do the usual metabolic processes. N What will poisonous bites look like? However, you should still be aware of some spiders with venom that carry extremely dangerous venom. The red back spider in Australia has a venom that causes nerve damage to humans for 24 hours. The black widow spider is famous for its poisonous bite, affecting the relatively strong nervous system, but it is difficult to cause death. When biting the spider spider, the wound becomes infected, leading to blood infection and gangrene. Tarantula large black spider in the rainforest will make people fall into a coma immediately. 6-eyed sand spider will cause local clotting and wound necrosis.
