Voracious carnivore, the polar bear has a privileged organism, which allows him to adapt to extreme cold.
The 'Arctic super predator' is one of the largest land mammals in the world and is characterized by having a completely white coat that allows it to adapt to its icy habitat.
His scientific name is Ursus Maritimus (sea bear), because he is an excellent swimmer and spends a large part of his life submerged in the frozen waters of the Arctic, where he has lived for about 120,000 years, according to the fossils found.
The largest polar bear populations are located in Canada (60% of specimens), Alaska, Greenland, Siberia, and Wrangel Island. It is believed that it derives from the brown bear and that it has mutated the color of its fur due to its habitat; Likewise, he also reduced the size of his ears and tail to be able to keep warm in such a cold space.
Regarding its appearance, it presents some more differences in relation to the other bears: its legs are more developed to be able to walk on snow and ice or swim long distances; the muzzle is more elongated, the coat is larger and has an additional layer of fat.
Although it may not seem like it, the polar bear's skin is black to catch the sun's rays and prevent heat loss in winter.
On average, adult males can measure 2.6 meters and weigh about 500 kilograms; meanwhile, the females have a height of 2 meters and a mass of 250 kilos. However, before giving birth, bears accumulate more fat and reach the same weight as males.
Polar bear: behavior and feeding
The polar bear is the most carnivorous ursus of all because plants hardly grow in the place where it lives, except for a few weeks in the summer. Its favorite prey is seal pups and beluga pups, although it can also consume walruses and seabirds such as arao.
An adult can eat up to 30 kilos of food a day. The funny thing is that they do not drink water, since it is acidic and salty in the Arctic; therefore, to hydrate it uses the blood of its prey.
The hunting technique is as follows: they make holes between the blocks of ice and, when the marine animal is sold to breathe, they capture it. In the case of land animals, it creeps up on colonies or nests.
Although it is a fairly solitary animal, it usually has some "friends" among other Arctic predators, such as foxes and wolves. These take advantage of the ferocity of the bear and its effectiveness when hunting to reach the carrion that it leaves behind.
Winter and reproduction
Polar bears do not hibernate, an exception for pregnant females. In addition, they suffer their habits despite the extreme cold and darkness of the region. With regard to reproduction, this is the only time that individuals meet and treat in a friendly manner.
Between April and May mating occurs. However, the female ‘saves’ the fertilized eggs (this ability is known as ‘delayed implantation’) so that they develop from September; meanwhile, it stores as much fat as it can.
Polar bears in the water
Mothers seek refuge in winter and give birth to two young in a shelter that they themselves dig in the ice. During pregnancy and birth, females do not feed externally, but feed on the accumulated fat; The kilos they have lost will be recovered in the sum
At birth, the offspring are blind, have no teeth and weigh 700 grams; Furthermore, they do not stand on their own until five months. From that moment on, the mother teaches them to locate food, hunt and protect the adult males, since in times of famine they can eat cubs.
After two years of being with the mother, the cubs leave the ‘home’. Finally, only at the age of four do they mature sexually
