polar bear characteristics
The polar bear is a fascinating animal that has the following characteristics:
It is quadrupedal, that is, it walks on its four legs, ending in sharp and short claws, designed for sea hunting.
Its fur is white and covers it completely, although underneath there is a rarely visible black skin. Beneath the skin and dermis they have a dense layer of fat that isolates the body from the environment, and that only thins on the head and snout.
The males of the species are usually about 2.6 meters long and weigh between 350 and 680 kg, while the females are around 2 meters and a few hundred kilograms less in weight. It is, therefore, a very bulky and heavy animal.
They are solitary hunters, endowed with a prodigious sense of smell and a bite of 86.83 kilograms-force per square centimeter, that is, stronger than that of the white shark or the Bengal tiger.
They have an amazing ability to swim: they can cover about 10 kilometers per hour of free swimming. However, their food is always produced in the dry. His skin is also waterproof.
They do not hibernate during the harsh arctic winter, and spend around 50% of their life time looking for something to eat.
