The seal has a round and smooth head, no obvious neck between the head and torso, and a short, thick neck, which is one of the remarkable adaptation characteristics of the harbor seal's life in the water. In order not to lose heat in the body and increase the buoyancy of the animal body in the water, its body has a very well-developed fat layer, so it does not matter if it is in a cold place.
The seal lives in such a cold environment, but it does not catch a cold, this is because they have a thick fat under the skin, which can not only keep warm, but also regulate their body temperature to adapt to the low temperature environment.
Seal. Seals, like whales, breathe with their lungs, and in the cold winter, in order to better ventilate on the ice, they will use their sharp teeth to carve out "skylights" in the ice, and after diving for a while, they will poke their heads out of the skylight to breathe, so that they will not be suffocated.

Seals rely on their own subcutaneous fat to fight the cold environment. It is a mammal that lives in water and has a spindle-shaped body with limbs more like fins, which makes it convenient for them to swim. It usually lives in cold temperate zones and usually rests on ice, but spends most of its time swimming and feeding in the sea, eating mainly fish, but also crustaceans and cephalopods.
-
The reason why seals are not afraid of cold is that seals have a lot of fat stored in their bodies, which has an excellent effect on heat dissipation. The fat is like a thick coat for the seal, which can still be at ease despite the perennial cold temperatures at the North and South poles of the Earth.

Seals live in such cold conditions, but they don't catch a cold because they have a thick layer of fat under their skin, which not only keeps them warm, but also regulates their body temperature to adapt to the cold environment.
-
Every living thing has its own suitable temperature. In the case of a seal, it is able to adapt to the temperatures of the sea, and its subcutaneous fat is particularly thick, so it is not afraid of the cold.
-
The seal has the most fat on its body, and it is this fat that allows it to survive the rain in cold glaciers, and it can withstand up to -100 colds.
-
Seals have a thick layer of subcutaneous fat, which helps them withstand the cold polar temperatures.
-
Because he has this fat on the surface of his body, it is said that it can carry some cold.

Seals in the Arctic.
Seals live mainly in the Arctic, near the Antarctic and in temperate or tropical oceans, and because of their small population, Antarctic seals live in Antarctic ice sources, so they are listed as internationally protected animals.
Despite their geographical location, all seals in the world have spindle-shaped bodies that are suitable for swimming and have rounded heads that resemble domestic dogs.
In the world's oceans, there are many living seal species, with the Antarctic being the most abundant, followed by the Arctic Ocean.
North Atlantic, North Pacific Ocean, etc.
Seal Habits:
Seals live in cold temperate oceans and spend the rest of their time swimming, feeding or playing in the sea, except during farrowing, resting and moulting seasons on ice, beaches or rocks. The breeding period is not clustered, and after the birth of the young animals, they form a family group and lactate.
After that, the family group ends. Giving birth on the ice, when the ice melts, the young animals begin to live independently in the water. A small number of individuals with a delayed breeding season have to give birth on sandy beaches along the coast. Fish is the main food, but also crustaceans and cephalopods.

The water temperature of the seal pool should not be higher than 20 degrees. Seals are afraid of heat and cold, but special attention should be paid to the water temperature of the original pool water and the water temperature of the new pool water must not exceed 5 degrees, otherwise the seal will catch a cold, and the salinity of the seal pool water is generally lower than 20 parts of a hundred percent of the salinity of seawater for farmed seawater.
Exterior features of seals
Seals are marine animals.
Mammals are viviparous, their bodies are streamlined, their limbs become fin-shaped, suitable for swimming, the sea leopard has a thick layer of subcutaneous fat to keep warm, and provides food reserves to produce buoyancy, the body of the seal is spindle-shaped, suitable for swimming with a round head, like a domestic dog.
The forelimbs are shorter than the hindlimbs.
The front feet of the seal are shorter than the hind feet, the hairy fins and feet are covered with nails, the nails are 5 toes, the ears have become very small or degenerate to only two holes, they can open and close freely when swimming, and most of them swim on the back feet, but the hind feet cannot bend forward, and the heels have degenerated with sea lions.
Unlike fur seals, it cannot walk, so when it moves on land, it always drags its cumbersome hind limbs and crawls with its body bent.

The reason why seals are not afraid of cold is mainly due to the special adaptability and physiological characteristics of their acacias. First, seals** have a lot of tiny hairs and flippers that help them swim quickly and stay warm in the water. At the same time, the seal body surface is covered with a thick layer of fat, which effectively prevents heat loss and can also provide buoyancy and protection when swimming and diving in the water.
In addition, seals have some excellent physical characteristics and behavioral habits that allow them to survive in extreme cold environments. For example, seals can keep their bodies functioning and surviving properly by regulating their metabolism to adapt to different ambient temperatures. In addition, seals have a cold-tolerant nervous system and immune system that are resistant to cold, humidity and other harmful environmental factors.
Seals on Earth have a wide range of distributions and can be found in cold regions from the Antarctic to the Arctic. Some researchers have also pointed out that seals have gradually adapted to survive in cold environments during the long process of biological evolution, which is one of the main reasons why they are not afraid of cold.
Overall, seals' physiology and adaptation to the cold allow them to survive in extreme cold environments, which is why they are an integral part of ecosystems in the Arctic and Antarctic regions. <>

Seals are afraid of killer whales, which are natural predators of seals. Seals are also afraid of sharks and polar bears, and they also hunt seals on high stools.
Seals are a general term for the pinniped subspecies seals, which are a kind of mammals with a spindle-shaped body and fin-shaped limbs, with a round head and a short neck, no external auricles, because their faces are long like cats, hence the name seal, to distinguish the other two families of the pinnipodae, the sea lion family, and the walrus family. They are highly adapted to life in the ocean, spending most of their time in the ocean, and are found throughout the sea, with the largest number along the Antarctic coast. Common ones are spotted seals, harbor seals, hooded seals, etc.

Seals are one.
A general term for the COPY section. There are many types of this Bai family, some of them are fierce, and some of them are more docile.
Usually the gray seals that are common in dao, etc., have a relatively mild personality, similar to the usual pets, and will have a good temper if they are not provoked after being familiar, and it is also easy to train, but the seals do not want the sea lion to stand on the hind fin, so the performance value is small, so there are few performances, in fact, it is relatively easy to domesticate.
Some of the larger species in the department, such as the leopard seal in Antarctica, can be evaluated with **, the staple food is penguins, and penguins that are often killed but not eaten are often found to be killed by them, and they are not hunted for predation. . . . In addition, the southern elephant seal, the largest pinniped, has a more fierce personality, which is inferior to the leopard spotted seal, but it often attacks the animals that enter its territory, and the fighting between males during the breeding period is also very fierce among animals, often covered with injuries, and it is only because of the thick fat layer that it is not life-threatening.
Generally, the ringed seals, spotted seals, bearded seals, etc., which live near China, are all species with good characteristics.

Possibly, dear. Seal oil is a fatty oil extracted from the body of seals and has long been used for pharmaceutical, nutritional, and cosmetic purposes. However, the mass killing of seals for seal oil has had a serious impact on seal populations.
In the early 20th century, demand for seal oil sparked widespread commercial hunting, which led to a dramatic decline in seal populations. In the Arctic in particular, including Greenland, eastern Canada and Norway, seal hunting has threatened seal populations in these areas. In addition, many seal populations remain under threat due to factors such as marine pollution and climate change in Honggaho.
At present, measures have been taken internationally to restrict the production, marketing and use of seal oil to protect the survival of seal populations. For example, the International Whaling Commission prohibits the commercial hunting of seals, and many countries and regions have enacted laws and regulations to protect and manage seal populations. In addition, modern technology and engineering are increasingly making use of other types of oils, such as vegetable oils and synthetic oils, to reduce the demand for seal oil.
In conclusion, widespread commercial hunting of seals for seal oil has had a serious impact on seal populations, but measures are now in place to protect these endangered species.
According to the British weekly "New Scientist", American university professors have cracked the reason why fish resist freezing. Until now, no one has been able to say exactly how antifreeze proteins help insects, fish and plants survive sub-zero temperatures. >>>More

Why penguins aren't afraid of the cold Antarctica is the coldest place on Earth, and the lowest temperature here has been measured to be 0 2 C. The penguins that live here are covered with dense and thick feathers, and the tips of the feathers are curved, like tiles on the roof, and even water cannot penetrate them. There is also a dense pile of fluff underneath the layers of feathers, like the best quality woolen sweaters. >>>More
That's because women like to wear less, highlight their lines and **, and show them to men.
We all know that natural selection, survival of the fittest, this is the law of nature. Once you don't adapt to this law, there is a risk of extinction. The sunfish's tail fin is severely degenerated, which causes it to swim slowly and be easily eaten by seals. >>>More
