The sugarcane beetle species mainly include the black scarab, the brown beetle and the large brown hairy beetle, which often arise and cause strong damage in sandy soil, riverbank soil, soil with light mechanical composition, or on specialized cultivation areas, growing sugarcane for many years, not rotating crops with other crops. NASU technicians check for insects entering the lamp trap. Photo: NASU. The life cycle of these beetles lasts from 365 to 720 days, going through 4 stages: egg, larva (worm), pupa and adult. Over the years, Nghe An Sugarcane Company Limited (NASU) has researched and applied integrated measures to effectively manage sugarcane beetles in the company’s raw sugarcane areas. This is the result that NASU has studied the management of sugarcane beetles in many countries such as China, Thailand, Indonesia… to apply on NASU’s sugarcane material area. Mr. Nguyen Hoang Son Phong, engineer of NASU said that sugarcane field was damaged by beetle larvae, yield decreased by 13-54%, sugar decreased from 11-57%. The original cane is more severely damaged by beetles than silk cane. Larvae (larvae) hatch from eggs, live in the soil for an average of 240 – 480 days (larvae of the brown hairy beetle are larger, longer than the beetle species) before transitioning to the pupa and adult stage. During the development cycle, larvae are active in the ground, age 1 and 2 in addition to eating cane roots, also eat organic matter, humus, decayed organic fertilizer or bagasse. Light traps are quite simple but effective in killing beetles applied in the cane material area of ​​NASU. Photo: NASU. From the end of the age of 2, the larvae only feed on the roots and underground stems of sugarcane. The 3-year-old larvae have a long sexual development time and cause the most damage to sugarcane, making sugarcane unable to grow, withering, drying and dying, leading to a decrease in sugarcane and sugar yield. The more damage the harvest stage, the more obvious. When the 3-year-old larvae are full, they begin to build cocoons out of soil and pupate to stay in the cocoon. If the weather conditions are favorable, after about 20 days, the pupae will turn into an adult, break the cocoon and crawl to the ground. Unfavorable weather conditions, especially low soil moisture and low temperature, will prolong the pupal development time. This extended period, called the hibernation period, can last up to 4 months. Effective management of beetles According to the research as well as the process applied effectively at NASU, control beetle larvae by plowing the soil thoroughly before planting sugarcane, collecting larvae and spreading the granular insecticide Patox 4GR, with the amount of 40 kg/ha in rows when planting sugarcane. Beetles trapped in nets. Photo: NASU. However, the method of spraying granular pesticides into the soil, in addition to killing larvae, will destroy beneficial microorganisms and insects in the soil, affecting the soil environment. The adults of these sugarcane beetles tend to be strong with light, fly out to mate from March to May, after showers with an amount of over 20mm. This is the best time to kill adults, limit egg laying, and reduce later harm caused by larvae. Mr. Hoang Quoc Tiem, a long-time sugarcane grower in Dua village, Nghia Yen commune (Nghia Dan, Nghe An) said that in the spring crop of 2021, in addition to killing larvae when growing sugarcane, NASU has implemented additional measures to destroy them. maturity such as using lamp traps, casting nets, and making traps in the field. The light trap is designed to be able to install light bulbs from the grid, battery lights or solar power systems. Traps are made by taking advantage of plastic containers, above are lights, below are placed water, add diesel oil to prevent the adults from moving out of the trap. In the middle of the light trap, install 2 corrugated iron sheets of size 40 cm x 60 cm, perpendicular to each other. As adults, beetles are attracted to light, flying into traps will collide with corrugated iron and fall into the water. After the rainy nights of early summer, each light trap catches 250-300 brown beetle adults, 40-50 black beetle adults, and 20-30 large brown-haired clipping adults and lots of adults of other sugarcane borers. The “product” obtained after a night of light traps includes many different species of beetles and borers… Photo: NASU. In addition, on the field, a fishing net is installed, the size of the net is 1cm x 1cm, and the adults move hundreds of fish of all kinds after every night it rains. In the sugarcane field, from 50 – 100m, dig pit traps, measuring 30 cm deep x 60 cm long x 60 cm wide, below the manure and by-products, which are the preferred food of adults, mixed with drugs. Low-odor insecticide is Goldra so that when adults eat it, it will be destroyed. According to the research results of scientists, the female beetle species can lay an average of 229-328 eggs, the lowest hatching rate from eggs to larvae is 70%. With the method of killing adults from light traps and netting in the field, it will limit a lot of harm caused by larvae to sugarcane … Mr. Phan Van Toan, Director of Agricultural Extension of Nghe An Sugar Co., Ltd. said that with the above management method, the rate of damage of beetles on both silk and sugarcane fields is reduced. This is the money for the company to expand the model on the raw material area in the coming years to stabilize the material area and improve production efficiency for farmers.

Many diners enjoy this dish with the outdoor space on the terrace of the restaurant in Paris, praising the food that is quite new to the European region. The ornate dish won many nods and compliments from the adventurous clientele. A chef from Paris who has just prepared a pasta dish of insects, sweet potatoes and sautéed larvae, said: “This is an ideal dish for beginners to eat insects. Their taste is quite attractive and very little. who don’t like it.” French restaurant serving food of the future is not for the faint of heart In January 2021, the European Food Safety Authority (EFSA) deemed the larvae of the beetle, Tenebrio molitor, fit for human consumption. By May 2021, this agency approved the sale of this ingredient in the food market. It is predicted that to meet the growing world population, insects will soon be included in the cuisine of the future. The European Food Safety Authority has studied more than a dozen different applications for insect food products, including crickets and locusts. Insects in general can provide a sustainable and low-carbon food source for the future. Local resident Soheil Ayari, after dining with her two daughters, said: “I feel like I’m in a traditional restaurant except for what I’m eating. But honestly, the taste is very good. like regular food”. Ayari’s young daughter is also very excited about the new dish, saying: “Insects are eco-friendly and more than that, they are also very good.” Laurent Veyet raises worms at the store, their food is porridge and vegetables. Although, at first glance, the larvae look like maggots unappealing to enjoy, they are in fact the larvae of beetles, which are rich in protein, fat and fiber. With a versatile ingredient, the beetle larvae can be used to cook curries, salads, or ground to make flour into pasta, cookies or bread. Stefan De Keersmaecker, spokesman for health and food safety at the European Commission said: “Insects are very nutritious. They really help us transition to a healthy diet and food system and more sustainable”. For chef Laurent Veyet, he faces a two-part challenge. It is about winning public opinion and learning how to create attractive insect dishes combined with a variety of foods. “You have to find the right flavors and the right accompaniments. That’s what any chef will tell you,” says Laurent Veyet.

Illustration. Powdered caterpillars are rich in protein The mealworm is a species of beetle in the family Tenebrionidae, known in English as Mealworms or mealworm beetle. In 1758, Linneus gave the scientific name Tenebio molitor. This species is native to Europe, is on the list of storehouse pests (cereals, flour and food), but is not serious. In Vietnam, mealworms are considered to originate from the Mediterranean, but are mainly imported from China through informal channels and considered as “strange weeds” (foreign creatures) with the name “Golden mealworms”. Powdery mildew larvae are widely sold in Hanoi and used as food for ornamental birds. Insects for animal and human food have received increasing attention in recent years. They may represent an alternative source of protein and micronutrients compared to conventional meat sources. Therefore, the objective of this work was to determine the nutritional value as well as the degree of chemical and microbiological contamination in order to better assess the risk/benefit of consuming mealybug larvae. These mealworm larvae have a nutritional value with 10.4% fat and 13.7% protein, similar to conventional meat sources. Their main fatty acids are oleic (37.8%) and linoleic (33.2%). The results showed that these larvae met the essential amino acid requirements (all above 100% of the daily contribution), with the exception of lysine. Study results also show that T. monitor larvae are an excellent source of minerals such as phosphorus, magnesium and zinc (114%, 109 to 128% and 117% of the RDI). Although, it is low in potassium and iron (16-17% and 20% of the RDI). The lower sodium content is a health advantage, as eating a lot raises blood pressure. The mercury and lead values ​​were below the detection limit and the cadmium level was 0.10 mg/kg. The larvae of mealybugs had a high amount of bacteria but no pathogenic bacteria were detected. Starving the larvae for 8 days at 5°C reduced the total number of microorganisms, especially yeast, and the total number of thermophilic anaerobic spore forming bacteria. Licensed by Europe as food Recently, the European Union Food Safety Authority (EFSA) announced that it has granted a safety certificate for the consumption of dried yellow powder worms. It paved the way for restaurants in the area to offer insect-based foods. The EFSA’s first approval of a food insect is a big step forward in helping insects find a “place” in the daily menu of people. This is the basis for EU officials to decide whether to allow the sale of this item in 27 countries in the region. The new decision also marks the first time the safety assessment process for an insect food has been completed by EFSA, as the agency aims to license the protein-rich food industry. Currently, in Europe, insects are still not on people’s menus. Because of psychological and cultural issues, different from the reality in some Asian countries such as Thailand, Cambodia, Vietnam, Hong Kong, China… However, with this decision, the industry expects the insect food market in Europe to grow rapidly in the coming years, reaching an output of 260,000 tons by 2030. Not only flour worms, rice worms (Zophobas morio) will probably not be far away from taking over all nutritious foods such as chicken, beef, pork, milk… to become the main source of protein for mankind. Future. Rice worm farming accounts for only 10% of the land area compared to cows, 30% of the area is for pig farming, 40% of the area is for chickens. Meanwhile, the level of protein supply of this worm is as high as that of the foods mentioned above. In Vietnam, although mealworms are only raised to serve ornamental birds, other insects such as crickets, ca cuong, chits, bamboo worms, black thorn ants… have been bred or exploited in the wild for trading. sold for human consumption. Other benefits Research results from Stanford University have informed the miraculous ability of mealworms. That is, they can eat foam plastics and other forms of polystyrene. There are some insects capable of degrading plastic such as the wax worm Achroia grisella and Galleria mellonella or the Mediterranean moth (Plodia interpuncella)… that can chew, eat and digest plastic as garbage bags. In the intestines of mealworms, there are many species of microorganisms capable of degrading polyethylene (PE). 100 mealworms are capable of consuming 34 – 39 milligrams of foam insulation, equivalent to the weight of a capsule per day. Larvae that eat all foam insulation are just as healthy as those that eat bran. The mealworm converts plastic into CO2, biomass and waste that can be broken down by bacteria. This waste appears to be safe to use as fertilizer for plants. They have designed a breeding area for mealworms with three purposes: Decompose plastic, provide food for people and use waste to make fertilizer for plants. The breeding area for powdered worms is made from organic glass (plexiglass) and is designed to be divided into 4 floors. The adults (male and female) will be kept on the top floor. Their eggs, when laid, will fall through small holes to the second floor. Here, the eggs will hatch into larvae and be fed sponge. As the mealworms grow, they are moved to the third lower floor. Here they are fed powder to cleanse their intestines and pupate. The mealworm droppings on the third floor will fall on the fourth floor and be collected to be used as fertilizer. At the third floor, we can collect the mealworms for food or let them grow into adults and then bring them back to the top first floor to continue the breeding cycle. Farms that raise mealyworm larvae can produce more edible protein than traditional farms that raise chickens, cows, pigs or dairy cows for the same amount of land used. The researchers compared the environmental impacts of a mealworm farm with that of traditional livestock farms using three parameters. These are land use, energy demand and greenhouse gas emissions. They found that for each unit of edible protein produced, worm farms required much less land and energy.

One day, while walking in the woods behind her home in Devon, Jo Brown was mesmerized by the sight of a green beetle perched on a leaf. Jo liked it so much that she quickly took a picture of the beetle as a document to bring back to draw. Jo Brown is very interested in exploring nature. As a nature lover, she has a passion for painting, so after the first illustration of a green beetle, Jo continued to work hard to draw more mushrooms, birds, and plants. , the flowers she knew in her home studio in Teignmouth. With just a simple pen and ink, Jo creates vivid drawings of the natural world, from the weeds in her garden to the wild nature of Dartmorr. For Jo, illustrating nature brings her much joy and inspiration. Each page is illustrated with Jo as a diary, in which she records the things she discovers from nature in order based on when she found them. Illustrating nature makes Jo very excited, she thinks that in the vast nature there are many things that are worth exploring, understanding, respecting and remembering. Jo has brought nature down, encapsulated in a diary – Video source: Twitter@bernoid After many efforts, Jo has launched a nature magazine called Secrets of the Devonian Forest at the end of 2020, a collection of illustrations that she miraculously made. With this magazine, Jo wants to bring nature closer to everyone, thereby inspiring people to explore the small things in the natural world around each person. By calming down, patiently observing your own small garden, or on the streets that you often pass by every day, you will encounter the wonders of nature that sometimes because of busy worries. or the noise of the city, we have overlooked those interesting things. Thuy Duong According to many sources

I thought no one would dare touch this ugly-looking beetle. But unexpectedly, Ca Nieng appeared in the list of specialties not to be missed when coming to the low-lying area. Photo: Internet If ca cuong is impressed by its pungent taste, ca cuong brings a unique nutty and rich flavor. The shape of the stick is similar to the “brother” with black wings and a small round body the size of a finger. Ninh Binh people also often call Ca Nieng “deep water”. Photo: Internet If you are a newcomer to the ancient capital, surely no one would have expected this to be a famous specialty of the ancient capital. This type of insect is not uncommon. In leisurely afternoons, people often go to the field to “sock” a few times to get a basket full of cassava to be processed. Cut off the legs, remove the wings, remove the belly and wash. Roast the eggplant like shrimp and shrimp with fish sauce and salt to taste, so you have a meal to bring rice. Photo: Internet The dish is somewhat modest and popular like that, but for the villagers, there is nothing like it. Stir in a bowl of hot rice and then pick up a piece of roasted coffee, so rustic yet delicious. Each of them creates a very unique flavor but is strangely combined. The fragrant sticky rice mixes with the greasy, crunchy texture of the spice tower. Sometimes you have to “clean” a few bowls. Photo: Internet The pleasure of enjoying roasted coffee is at the end of the meal, take a piece of burnt rice for a few fish and then curl it, bite it lightly and slowly chew it, the country flavor spreads gently in the throat. Although there are countless dishes from the garden, but Ca nieng has a unique and unmistakable taste. Having the opportunity to visit the beautiful land of Ninh Binh, do not miss the opportunity to enjoy these rustic but rich local culinary culture.

Aphids is a type of beetle, most commonly found in Bay Nui, in two districts of Tinh Bien, Tri Ton (An Giang) and the southwestern border region. Aphids reproduce in large numbers at the beginning of the rainy season and last for about a month. This time is usually from April to May of the lunar calendar, depending on whether the year rains sooner or later. In the past, leafhoppers were considered harmful insects for farmers because they often bite young shoots, especially in mango, mulberry, and cashew trees… But recently, people in the border areas have discovered it. how to fry aphids, turn this insect a delicious and nutritious dish. Since then, many people have sought to hunt to process aphids into a unique delicacy, notably the deep-fried mealybugs. The beetle has a beetle-like shape, the size of a thumb, brown cockroach wings, short body, wings, very hard head and legs, but soft and round body. The sage beetle is dry, does not bite like some other insects. The people of this country consider this a “unique” dish, only eating for 1-2 months a year. Therefore, new beetles become a specialty. The way to catch leafhoppers during the day is to pick up cow dung, dry buffalo dung and burn it for smoke to rise to the sky. After a while, the beetles smelled the smell and just flew away, dancing in the smoke. People kept holding brooms to beat the bugs to the ground and then put them in baskets. Hunting beetles at night is simpler and more gentle. The catcher just needs to hang a bright lantern right under the mango tree, where there are beetles gathering on the tree. Just a few minutes later, the light-loving beetles were flying and falling on the ground. The Bay Nui leafhopper is larger than a thumb with a characteristic shape of the beetle, so it looks “difficult to swallow”. However, when they have passed through the hands of the housewives in the mountains, they seem to have completely molted. In the past, beetles were considered the food of the poor. But today, this insect has become a specialty, becoming a favorite dish not to be missed in restaurants and pubs. Just like how to process rice crickets, nymphs or scorpions, hoppers only need to be cleaned by removing wings, legs and gutting, then rinsing with warm water mixed with salt. Then, the cook marinated the beetles with sugar, MSG, pepper, and garlic for about 20 minutes, then caught the pan to fry until crispy. The food stalls and restaurants will have a beautiful presentation, while the dishes of the people in the countryside are simple and rudimentary, but the taste is also crispy, fragrant, fatty, and not inferior. People who know how to make aphids when removing their intestines will not squeeze all their eggs, because the eggs are very delicious and fatty, once eaten, they will remember forever. Crispy fried beetle can be served with raw vegetables, tomatoes, cucumbers and salt and pepper with lemon. Just like eating fried scorpions, people who eat aphids for the first time often feel scared because the animal is ugly and the color is not fresh and attractive. The eater just needs to put it in his mouth to bite, the taste will immediately spread, the fat of the meat penetrates into each tooth root, not mixed with any other flavor. Photo: IT.

Along Highway 14 to the inter-commune roads of Hon Quan district (Binh Phuoc) these days, we can easily see cashew orchards, mango, bare leaves because of beetles (people also call are beetles) harmful. Locals said, beetles appeared here nearly ten years. However, the previous years were not significant. Close-up of a beetle that damages plants in Binh Phuoc. Photo: TT. This year, for some reason they appear quite dense. Currently, people are very worried because the leaves of the plants have been eaten up, resulting in loss of photosynthesis, the plants are depleted, output has decreased, or even died, while not knowing how to effectively prevent and treat. Recognizing the fact that at some mango orchards in Dong No commune (Hon Quan district), drizzling weather for many days is a favorable environment for beetles to multiply and develop. In some orchards, there has been a phenomenon of beetles biting leaves, limb branches, and even many gardens leaving only young fruit hanging. Growers have bought pesticides to spray but have not been able to prevent the onslaught of beetles. Ms. Pham Thi Huyen Trang in Dong Tan hamlet, Dong No commune has 7 hectares of mangoes at harvest age, but in the past few days, beetles have caused nearly one third of the mango area to be destroyed and there is no sign. stop. With the method of spinning the lights, every day she catches tens of thousands of children. However, this method does not appear to be effective due to the large number of bugs. “Now the beetle has eaten all the young leaves of the mango tree. If not, in a few weeks, all the leaves of the mango tree will be eaten up. With this situation, mango trees will inevitably be depleted, the next year’s crop will decrease yield “, Ms. Trang worried. Similarly, nearly 1 hectare of mango and cashew of Nguyen Huu Cong’s family nearby were also gnawed clean by beetles. Mr. Cong said that when he discovered beetles, his family bought pesticides to spray, but only a few days later they reappeared. Many orchards were bitten by beetles, leaving only their branches. Photo: TT. “After more than a month of being eaten all the leaves, the trees are sprouting again, but the spreading bugs continue to attack. With this situation, surely the trees will be depleted, the next season’s yield will drop sharply, some trees. We hope the authorities will consider the reality and take measures to support farmers to prevent this insect “, Mr. Nguyen Huu Cong suggested. Not only harming plants, beetles also upset the daily life of people. Beetles are mainly active at night, only need to see the light that they come in, making people here not eat and sleep. Many households, in order to limit bugs from entering the house, people have to close their doors and turn on the power in the yard and then “entrench” in the house. Mrs. Ho Thi Dai from Hamlet 3, Dong No Commune, Hon Quan District shouted to heaven: “My house is next to the cashew garden, so it was affected a lot. Although the house was closed at night, beetles still entered through the places. When they fall onto the floor, bugs release a red substance that looks like thin blood. At night they crash into the roof of the roof, making a noise that causes sleeplessness. Need a radical solution Concerning this issue, Mr. Tran Hai Ha, Head of Department of Agriculture and Rural Development of Hon Quan district, said that the unit has grasped that beetles attack and damage plants in the area. “There are many communes in the district that are attacked by this beetle. We are giving statisticians the area and extent of the damage of the households,” said Mr. Ha. Not only cashew trees, many mango orchards were also attacked by beetles, leaving only the fruit and branches. Photo: TT. According to Mr. Ha, 2 weeks ago, the district Department of Agriculture and Rural Development worked with the District Agricultural Service Center to give directions to deal with this problem. Mr. Ha said that these bugs are difficult to destroy, not as easy to spray as common insects. Currently, the Department of Agriculture and Rural Development is waiting for the Center to come up with solutions to help people prevent this species of bugs. Regarding measures to control this beetle, Dr. Nguyen Van Bac, working at the Bu Dop District Agricultural Extension Center (Binh Phuoc), said: In the world there are 200 types of beetles, rarely seen for leaf-eating beetles. described in national documents. Most likely, this beetle belongs to the type of beetle that eats leaves of mango (Chafer beetles), scientifically known as Apogonia sp, belongs to the family Scarabaeidae, order Coleoptera. Harm mainly on trees of industrial trees and fruit trees such as palm, coconut, cashew, mango … According to documents, leaf-eating beetle eggs are laid in blocks, near the base, consisting of many eggs, each egg is wrapped in a hard layer of soil. Eggs are 1.0 – 1.3 mm long, white, bulging and round later. The incubation period is about 9 days. The newly hatched larvae are about 3 mm long and reach 15 mm before pupating about 10-11 weeks later. Lungs live in the soil, eating the roots of a variety of crops, weeds and decomposing organic matter. The larval stage is about 72 days long; pupae 2 – 3 days; pupae: 7 – 10 days; life cycle is about 3 months. At first time the city is brown, then it turns black. A beetle destroys things. Photo: TT. In the Southeast in general, Binh Phuoc in particular, bugs often outbreak and cause damage at the beginning of the rainy season (April – May). After dancing, bugs eat leaves, young branches of wild plants and plants. They mainly feed at night, and during the day they live hidden under the topsoil. For prevention and treatment, Dr. Nguyen Van Bac recommends that there are 3 methods: manual measures, which can use light traps at the same time in areas where many harmful beetles appear. Chemical measures, using active insecticides Permethrin, profennophos to spray in the evening. Biological measures, using bacillus thuringiensiss (Tricho-BT), Metarhizium anisopliae (green fungus) to spray on plants and in the soil to kill eggs and young offspring before becoming larvae. Currently, beetles continue to cause harm on many cultivated areas in Hon Quan district and are at risk of spreading to a large extent in neighboring areas. The most effective is the light trap The Department of Plant Protection said: Through working with the Agricultural Service Center of Binh Phuoc Province and the Agricultural Service Center of Hon Quan District (Binh Phuoc), it was known that this beetle appeared in recent years, usually arising from the beginning of the rainy season (April), extending to the middle or the end of May will decrease (actually, by May 10, 2021, it has decreased compared to the previous month). Many farmers in Binh Phuoc worry because beetles continue to damage crops and upset their daily lives. Photo: TT. Adult beetles are nocturnal, eat all kinds of leaves (cashew, mango, rubber …) and have a strong tendency to light. Therefore, the safest and most effective measure at present is to use light traps (high capacity will attract more power), underneath put a water basin with a layer of active petroleum scum, and beetles plunge into the falling lights. water pots, oil scum will seal the breathing holes on the two sides of the beetle stomach, causing rapid death. On May 10, 2021, the Plant Protection Department sent a mission led by Mr. Do Van Van, Director of the Southern Regional Plant Protection Center (under the Department of Plant Protection) to Binh Phuoc to understand the situation, take samples of beetles and send them. appraise to know scientific names, from which to grasp habits, biological characteristics, host plants to determine the most suitable and effective control measures. The Department of Plant Protection also confirmed that this beetle has appeared in Vietnam for a long time, not the main pest on crops in Vietnam. In recent times, a number of new species have arisen, such as the “black bean” beetle, the coffee beetle in Kon Tum, and the forest leaf-eating worm in the city. Ho Chi Minh City, Binh Duong, Dong Nai … They are pests on forest trees, but when their numbers break out, they spread to harm crops or affect people’s lives, but not harm (such as “black beans”). Also according to the Department of Plant Protection, in 2018, a similar species of beetle also appeared harmful to coffee young leaves during the basic construction phase in Dac Ma commune, Dac Ha district, Kon Tum province, but with a smaller size. The result of identification is species Maladera castanea, family Scarabaeidae, order Coleoptera. The Central Center for Plant Protection (under the Department of Plant Protection) has cooperated with Kon Tum Plantation and Plant Protection Department to guide farmers to apply the method of attracting light traps to kill beetles and protect coffee trees in recent years. ..

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.

Red tree bark flattened beetle

This beetle about half an inch long has a habitat from North Carolina to the Arctic Circle. They live under the bark of a tree and their bodies are purposefully designed to survive the harshest conditions in mid-winter.

The arctic climate in August acts like the resting climate for this species. In laboratories, they can withstand freezing temperatures up to -150 degrees Celsius.

In fact, this is the coldest we’ve ever seen. They can overcome this extreme cold by forcing 30-40% less water in the body and preserving the remaining water by using antifreeze proteins between the cell membranes.

Thyme beef

Muskrats have lived in the Arctic for a long time, from the ice age about 200,000 years ago. With double-layer coat, the first layer is a thick dark gray outer coat that reaches the ground long and the inner undercoat gives them very good resistance to cold to temperatures down to minus 40 degrees. , to withstand the rigors of the Arctic.

Muskrats live in herds from 12-24 in winter and 8-20 in summer. During the summer, musk cows live in humid areas, such as deep valleys, and move up into higher mountainous regions in winter. Their food includes arctic willow grass, lichen and moss under the snow. Thyme is raised for meat, milk and feathers. Currently this species is protected, so the number is kept at a stable level.

Great Greenland shark

The Greenland giant sharks live in deep waters in the North Atlantic and Arctic regions, and these giant sharks not only survive in the cold water, but also have the longest lifespan of any species. are there any vertebrae on the planet – an average of 300 to 500 years old.

Greenland giant sharks have an extremely slow metabolic rate that helps control temperature and prolong life, and they are also the largest shark, can reach 6.4m in length and weigh about 1,000kg . Therefore, this shark is also very slow, often only hunting prey that has gone to sleep.

The price for a 500-year-old shark’s longevity is also not small. Specifically, it not only swim very slowly, difficult to find food, but the body also contains many parasites. Sometimes it even has to eat scavengers to relieve its hunger.

Besides, scientists are also hoping, the study of 500-year-old shark’s DNA could open a way to longevity for humans.

Before that, indigenous people in Greenland and Iceland used to believe in increasing longevity by eating Greenland shark meat.

Greenland shark meat is considered a specialty in Iceland, although toxic if not handled properly.

Snow Sheathbill

The snow Sheathbill is a brave, white, dove-like bird; This is the only native bird that lives on the surface of Antarctica and is the only species to breed here.

With their thick fur to help keep them warm, they live mostly on the ground, trying to pick up other birds’ scattered food scraps. They are also the only birds in Antarctica that do not have membranes.

So how can the snowy Sheathbill keep his toes warm while spending so much time on frozen ground? The secret lies in their life-long “bounce hobby”, they spend a lot of time hopping from leg to foot in order to reduce the coldness from the surface of the ice and snow. Furthermore, Snow Sheathbills also possess an extremely thick, fine coat that helps them retain heat well.

Weddell seals

If you are looking for a mammal that loves a few dozen degrees of negative cold every minute, then you will definitely love the Weddel seal.

They are the farthest Antarctic species of any kind, and spend most of their time living underneath the Antarctic ice, where they can hunt and avoid being caught by killer whales.

With the ability to dive deep to a depth of more than 600 meters, Weddell seals can stay underwater for up to 45 minutes and if they cannot break the ice to get the oxygen they need, they use their teeth to dig a hole. take the gas.

Antarctic seawater is actually warmer than surface air (which can drop to -70 degrees Celsius), so especially during intense winter storms, seals will stay warm by diving into the ocean. .

The arctic soil squirrel

If the current epidemic in the world makes you want to hibernate, you can consider the Arctic ground squirrel as an example.

Living in the arctic tundra in North America, where temperatures can drop below -63 degrees C in winter, they can escape the coldest winter by burrowing underground and sleeping for as long as eight. the month of the year.

When hibernation, the temperature in the brains of these squirrels can drop to just above freezing, while the body temperature can drop to -2.9 degrees C and the heart rate drops to just one beat per beat. minute. When the hibernation time is over, the squirrels need about three hours to warm up the body again.

This ability of arctic ground squirrels is due to them being able to cut off nerve connections and synapses to hibernate, then reconnect them immediately after awakening and warming the body, almost 2 – Every 3 weeks during winter.

In addition to its sublime cold tolerance, the arctic ground squirrel is also famous for its ability to fast for 8 months. The arctic ground squirrel body has the ability to recycle its own nutrients during hibernation for many months.
