Unlike the Arctic, where many countries around the world have built their own bases to serve a number of fields both in terms of science, economy and military, for Antarctica, this is still an unofficial land. government although the countries closest to it are Argentina, South Africa and Australia. Every year, during the winter, Antarctica does not receive any sunlight for 6 months; In summer, the sun is always on the horizon. Most of the sunlight falling on Antarctica is reflected back by the white ice, 1.9km thick on average, plus the highest terrain in the world (2,800m above sea level) giving this place its climate. coldest on earth. In the middle of summer, when the sun is perpendicular to the Tropic of Cancer, the average temperature in Antarctica is -25°C. In winter, when the sun moves down the Northern Hemisphere, Antarctica is as cold as -65°C and in some places -89.2°C. A cruise ship takes visitors to Antarctica Initially, only seven countries made claims, including Argentina, Australia, Chile, France, New Zealand, and Great Britain, by setting up facilities in the name of scientific research. Some other countries such as India, Italy, Russia, USA, Pakistan, Ukraine… although not claiming sovereignty, they also build long-term and sustainable constructions. In 1959, after much controversy, in order to prevent military conflicts, the United States, Great Britain, the Soviet Union and nine other countries signed the Antarctic Treaty, which essentially “set aside territorial claims” and use Antarctica for peaceful purposes only. Jane Francis, head of the Antarctic Survey, UK, said: “In 1980, five more countries made claims to sovereignty and now, 54 countries are present in Antarctica with 75 research stations. That poses many problems that need to be solved, such as climate change, fishing, tourism, resource exploitation…”. The results of 50 years of observations show that temperatures in some areas of Antarctica are rising much faster than the global average. This leads to melting glaciers and consequent sea level rise. Marine biologist Damon Stanwell-Smith, who first visited Antarctica more than 25 years ago, said: “Things have changed rapidly and we can see clearly. Just six years ago, there was Areas that are not accessible by boat during the winter are now experiencing large currents, allowing tour operators to bring tourists to visit Antarctica. Still according to Damon Stanwell-Smith, from November last year to April last, despite the raging COVID-19 pandemic, 51,000 tourists set foot on Antarctica, an increase of 17% over the previous year and will continue to grow. continues to increase even though the tour price is from 1,000USD to 100,000USD per person depending on geographical distance. “In addition to the 33 ships registered with the Antarctic Treaty Secretariat, there are 20 other ships under construction, not to mention the kayaking or air-plane tours that make Antarctica an oasis,” Mr. Damon said. play uncontrollably…”. The majority of tourists to Antarctica are Chinese, second only to the US in the ranking because Beijing is investing heavily in the continent, as part of its plan to become a “polar power”. What is Antarctica when the Antarctic Treaty is no longer in place? The Protocol on Environmental Protection to the Antarctic Treaty was adopted in 1991. It entered into force in 1998 and is the main instrument related to the conservation and management of biodiversity in Antarctica, in which There is a ban on exploitation of natural resources. However, after 50 years, the countries that signed the Antarctic Treaty can decide to amend the fishing ban provided that at least three-quarters of the current consultations – the 29 countries of the Antarctic Treaty – agree. Notice when the 50-year period will end in 2048. Whales slaughtered at a logistics base in Antarctica However, before the Environmental Protection Protocol to the Antarctic Treaty, seal hunting in Antarctica was practiced as early as the 18th century by the British, Norwegians, Argentines and Chilean. Meanwhile, large-scale whaling in Antarctic and sub-Antarctic waters increased sharply in the early 20th century, mainly by Norwegian and British companies. Whaling logistics stations erected in Antarctica are implied to be part of that country’s territory because, under international law, state activity is a key element of ownership territory. It is therefore not surprising that it is expressed in many forms by all the claimants to Antarctica, from scientific research facilities to dormitories for experts, rescue stations or offices that maintain navigation, airports, logistics, harbors, lighthouses, not to mention that some governments license whaling, seals, The establishment of national parks, the issuance of postage stamps, the mapping and naming of each area, etc., are concrete examples of the race to own Antarctica. According to National Geographic, UK, an increasing number of activities are damaging Antarctica, such as legal and illegal fishing, including the molluscs it contains. is the main food for whales. Arthur Devries, a fish biologist at the University of Illinois, USA, said that since 2003 he has not found an adult toothfish in Antarctica while in 1970, he caught 500 fish for a season to study a protein in the body of fish that helps make anticoagulants. Environmentalist Huck Dulown of the University of Gundee, UK, says he has collected hundreds of meters of damaged nets left behind by fishing boats, not to mention engine oil and household waste. travel. Huck Dulown said: “There are places called ‘scientific research stations’ but maybe inside are not military bases and it is not excluded that it hid missiles with nuclear warheads as it once happened. It goes against Article 1 of the Antarctic Treaty: “Antarctica shall be used for peaceful purposes only. Any measures of a military nature, such as the establishment of military bases, the conduct of military exercises, the testing of any weapon, are prohibited. Antarctica is humanity’s last unspoiled reserve. Under the ice of this continent is an extremely large mineral resource including oil, copper, gold, titanium, uranium, rare earth …, and the surrounding seas are inhabited by many types of creatures. In addition, the glaciers in Antarctica contain 90% of the fresh water in the world, so South Africa, for example, was planning to pull an iceberg to serve the freshwater shortage in the city of Cap Town. A scientific research station in Antarctica And although Antarctica itself is a demilitarized zone, armed conflicts have arisen in a number of its vicinity, including Chile and Argentina over an island near Cape Horn, as well as claims to the South China Sea. The two countries’ overlapping territorial claims, or the war between Argentina and Great Britain over the Falkland Islands, is the gateway to Antarctica. Although the war ended long ago with the victory belonging to Britain, according to observers, it is very likely that it will flare up again. Jim Tymothy, a professor in the Department of Geopolitics, Yale University, USA, said: “The fate of the territories in Antarctica depends on the coordination of the great powers. If coordination is not achieved, the continent will share seven in the next 20 to 30 years, and that could lead to an Antarctic war, is based on these factors: The emergence of technology that allows the rapid and economical supply of fresh water from glaciers in the South China Sea. Antarctica to dry regions, rising oil prices and increasing demand for crude oil Besides, food also needs to be exploited more due to the growing global population, which requires fishing in Antarctic waters…”. At the moment, there is no such convergence of interests, but more than ever, it is likely to take shape because over 60 years, up to now, 54 countries have joined the Antarctic Treaty. including 29 European countries, 9 Asian countries, 8 South American countries, 4 in North and Central America, 3 in Oceania and 1 in Africa. Not only that, the number of consultative parties of the Treaty with bases in Antarctica is also constantly increasing: Australia, Argentina, Belgium, Brazil, Bulgaria, Czech Republic, Chile, People’s Republic of China, Korea Countries, Ecuador, Finland, France, Germany, Japan, UK, India, Italy, Norway, New Zealand, Netherlands, Peru, Poland, Russia, Spain, South Africa, Ukraine, Uruguay, USA and Switzerland. The remaining 25 countries join the Antarctic Treaty as non-consulting parties but still have the right to attend relevant meetings without being included in the decision-making process. However, although “not included in the decision-making process”, these 25 countries still assert their position in Antarctica through scientific research stations, airports, ports, logistics facilities, etc. So the Antarctic race probably hasn’t stopped yet because no one is sure that in the future, no country will send people to this cold continent…

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.

The Greenland shark is a shark indigenous to the North Atlantic waters around Greenland and Iceland. They have a massive body, the size of a ferocious white shark, 6-7m long, weighing over a ton. As a carnivore. So although the “gentle” one of the “family”, Greenland sharks are still quite dangerous. Usually they eat small fish in cold seas, however they also sometimes catch seals. Despite its giant stature, what attracts ocean scientists more than that is the longevity of this ancient fish. Humans have been looking for ways to prolong their life, and it seems that the Greenland shark is the key to longevity. Biologist Julius Nielsen of the University of Copenhagen (Denmark), after a lengthy study, had to say: “From the beginning, we had expected them to be longevity but did not expect them to live that long. “ Usually sharks are about 30 years old. But in Greenland sharks, this is just the age “know how to crawl” … using the carbon measurement method, the scientists confirmed the average life expectancy of the Greenland shark is over 240 years. Even the oldest specimen is 512 years old – super longevity This means that the sea monster was born from the time Cristoforo Colombo discovered America, and lived until smartphones flooded the planet. Researches suspect that the extremely slow growth, growing only about 1 cm each year under the cold water has helped the animals to live a long life. Until the age of 150, Greenland sharks are fully mature, entering the reproductive age. Currently, scientists are still hoping to be able to find, separate and map genes that are directly related to this species’ longevity. In addition to longevity, large size, Greenland sharks also contain many interesting secrets, for example, they swim very lethargic. Unlike the terrifying speed of the white shark, the average Greenland shark only swims over 1km / h. When hunting prey, it can increase … 2km / h, only half the speed of human walking. Because of this “crawling” speed, scientists believe that it can only catch seals when prey is asleep. There is also an opinion that because it does not need to spend too much energy on moving, plus the cold water of the North Atlantic helps to “preserve fresh” the cells in the body, making Greenland sharks live. to 5 centuries. Adding a perfect factor for longevity is that this sea monster has almost no natural enemies when hiding its giant body forever on the ocean floor. The species that most threatens their lives is humans. This kind of confrontation in reality is completely absent Originally, Greenland sharks live in cold seas, so the body has to secrete a special substance to keep warm, preventing them from freezing. This substance for humans is extremely poisonous, but not so that the animal is ignored … As early as the Viking era, the indigenous people of this cold land discovered that burying sharks for several weeks removed the toxin. … To this day, it is well known that just boil the Greenland shark meat many times, it will achieve the same result. After 3 – 6 months, when the fish goes through a freezing cycle, they dig up and hang the carcass in the wind, for at least 9 months. In the end, just cut off the brown skin, take the white flesh inside, and we have a local specialty called Hákarl However, when trying to eat Hákarl many people say that it “tastes of nightmares” with a scent like urine, rotten cheese. Going back to the deep ocean, the Greenland sea monster also has another strange feature, that is, they are all blind … As a curse, this shark gets attached to the eye by the copepoda parasite, damaging the lens layer In return, Greenland sharks have a sharp sense of smell, can smell prey from extremely far distances. After all, it doesn’t matter much to not seeing anything on the undersea of ​​the sea. Until now, this sea monster is still an interesting research topic for scientists around the world.

Montauk is named for the tribe that calls it home https://dulich.petrotimes.vn/ Although known as Montauk, the land was actually first occupied by the Montaukett tribe – this is where the town’s present name comes from. The first settlers arrived in the area in 1648 and it took almost two decades before the land could be purchased. Views of the ocean are endless https://dulich.petrotimes.vn/ The Montauk lighthouse is known for its presence on the East Coast as a literal beacon because it remains active and emits a flashing light after five seconds that can be seen for 19 knots. However, for those with a chance to climb all of its 137 iron steps, the view from a height of more than 100 feet (more than 30 meters) on the slopes is unbelievable. A storm once separated Montauk from the rest of the United States https://dulich.petrotimes.vn/ When driving to Montauk, it’s easy to believe how this might happen. With such an isolated place, there are many paths in and out of Montauk. It is a two-lane road surrounded by trees and sand dunes on both sides. During Hurricane Carol that hit New England in 1954, the road and surrounding land leading to Montauk were completely submerged, temporarily becoming its own island. One of its buildings is 200 years old and that is not the lighthouse https://dulich.petrotimes.vn/ While the lighthouse itself was built by order of George Washington, it is not the oldest structure in Montauk since the lighthouse was built until 1796. The oldest structure is actually called. It is a second home and is used as a home for shepherds to look after livestock on the grasslands of the area. “The fishing capital of the world” https://dulich.petrotimes.vn/ According to Housely, Montauk is also known as the “fishing capital of the world” because there are so many giant fish species caught on its shores. In fact, the catch here is very good. It is also known to be the largest fishing fleet in the entire state. https://dulich.petrotimes.vn/

Fresh and dried seahorses and sea dragons are available for sale at Ham Ninh market. With fresh seahorses, it costs about 5 to 8 million VND / kg, but if bought retail, a pair of large seahorses cost about 80,000 VND, the smaller pair, about 40,000 VND. With dried seahorses if straight tail (dried while alive) costs 70 thousand VND / fish, while the dried seahorses cost about 40 thousand VND / fish … The market of Ham Ninh fishing village is located right next to the wharf and for those who first come to Phu Quoc will be surprised to see countless fresh seahorses almost all colors brown, black, yellow, pink … all kinds are sold in large pots, small pots, with oxygen tubing. In the provinces bordering the western waters of the country, Phu Quoc is considered the largest natural seahorse beak. January to April each year is the breeding season of seahorses when they find rock caves, dead coral reefs … to mate. This was also the time when Phu Quoc fishermen caught the most seahorses and sold them crowdedly in Ham Ninh market. In addition to customers who buy for self-treatment and processing, many vendors at the “miracle” market are willing to soak for customers with “miracles” … … from cleaning seahorses and sea dragons to selling both. white wines and bottles or jugs for soaking. According to Ut Map, who has sold seahorses in Ham Ninh for more than ten years, with seahorses, saliva works best, second is the eyes. When soaking in alcohol, fresh seahorses will produce saliva, so the effect is better than dried ones, so if soaking 10 fresh seahorses, with dried seahorses to soak up to 20. Seahorses here have two types, spiny type and non-spiny type. The spiny-free type is purchased faster by the middlemen because the wine is less fishy when soaked like the spiny fish. Because of the use of seahorses for the health of men passed from each other, Ham Ninh is considered to be a place that specializes in selling all kinds of “preventive medicine”. In addition to seahorses, also known as walruses, there are sea dragons, which are similar in use to seahorses, which are widely sold in dry food stalls. Along with seahorses, many visitors are overwhelmed by another kind of “miracle” that is probably only available in the “miracle” market, which is seal seal, sea cow seal is hung or sold right on the front plastic trays store. Another kind of miracle that the gentlemen are looking for is sea cucumber, but in Phu Quoc it is quite rare, but at the Ham Ninh market it is still present. Although it is a natural seahorse beak, but in Phu Quoc this very cute animal is being caught in the way of salvation and destruction due to the large purchasing power of tourists. According to incomplete statistics, each year about 1 million seahorses are caught in the waters of Phu Quoc.

Bright Side brings together 10 rare creatures that are on the brink of extinction. Global mountain gorilla Currently the mountain gorilla has increased to about 1,063. They can only be found in protected forests. This is evidence that conservation efforts can bring a species back on the brink of extinction. However, illegal human hunting remains a major threat to the fauna of Bwindi-Sarambwe. Sao la The saola species was discovered in the Annamite forests of Vietnam. The main threat to saola is hunting activities and environmental climate impacts. That is why many conservation organizations have collaborated to create a safe environment for them in nature. Animal with dunnart bag This tiny creature can only be found on Australia’s Kangaroo Island, with an estimated population of less than 500. The widespread cleaning of the vegetation by humans has put the dunnart in a very dangerous situation. In addition, wildfires in Australia in 2019 and 2020 have burned 95% of the species. That is why a closed sanctuary was created to keep dunnart and other endangered species safe. Iberian lynx This rare species can only be found in the jungles of southwest Spain. From 1985 to 2001, their population decreased by 87%; So far, there are about 400 lynx in the wild. Their natural habitat continues to be destroyed by new highways and cut down trees. Black-footed ferret While people thought they were extinct, tiny creatures have proven to still exist. However, their population is rapidly declining due to disease and the loss of their natural habitat. Their total population is estimated at around 370 in the wild. Massive restoration efforts by many federal agencies and zoos have provided space for the weasels to survive. Gharial crocodile In 2010, only 15 crocodiles were found in the Gandak River in Bihar. That’s why in 2014, a conservation initiative freed 30 crocodiles from captivity and returned them to the river, and their population began to increase. Kakapo For the first time in 70 years, the kakapo population is increasing with about 213 species of birds existing. Only during the 2018-2019 breeding season, 71 young survived, which is a record number for this species. The recovery team tries to make sure the birds stay healthy and protected from infection. Their next goal is to find a good habitat for the birds as disease is their main threat. Canadian harbor seals Found in Quebec, this is the only species of its kind that can only survive in fresh water thanks to fish. To date, only more than 100 live in the area. The cause can be attributed to human hunting. Also, in many cases, seals get trapped in their gears and cannot free themselves. Leopard Amur This leopard has found a way to survive in the jungle in the Russian Far East. They live up to 15 years in the wild and more than 20 years in captivity. They have an amazing ability to run very fast and jump high. However, the loss of habitat and human activity has reduced their number to about 84 individuals. Vaquita dolphin This very rare marine mammal was discovered only in 1958. However, in recent years, vaquitas dolphins have been victims of illegal fishing activities. They are often trapped in fishing nets. That is why their population is only about 10 in the Gulf of Mexico. They can be found in shallow water but will quickly swim away if a boat approaches them.

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.
