 polar bear adaptation


The polar bear is characterized by several features that help it adapt in its environment and practice its various activities. The following is a summary of the most important of these features:

swimming 

The polar bear is good at swimming skillfully, it can travel long distances across seas and bays effortlessly and at a great speed of up to 10 km / h, which is approximately 3 times faster than the speed of humans in swimming , and it is worth noting that the polar bear can close its nose while it is under water; Which helps him to swim. 

Diving 

The polar bear can dive superficially and not deep when chasing prey or searching for food. Determine the longest time a polar bear can spend in diving, and they estimated that it is unlikely to be at a depth of 6 m or more, and so far the longest period a polar bear has spent diving without rising to the surface of the water is 3 minutes and 10 seconds, during which it was able to Travel distance between 45-50 m.

camouflage 

The color of the white fur covering the polar bear's body plays an important role in its adaptation to the white snow and ice environment; This helps him to hide from enemies and camouflage. 

Regulating body temperature 

The thick, insulated fur that covers the polar bear's body and the thick layer of fat that accumulates under its skin helps it adapt to the frigid arctic environment; It can maintain its body temperature around 37°C, and its self-adaptation depends on its location, as it adapts through fur while it is above water, and adapts through a thick layer of fat while it is under water, and it is indicated that the thickness of this layer Fatty can reach 11 cm, and it increases as the polar bear gets fatter.
There is fur on the bottom of the polar bear's feet; This is to help him adapt to the severity of the cold and enable him to walk well and easily on the ice, and the polar bear seeks to maintain an appropriate temperature for its body; Therefore, he gets rid of any excess heat through certain parts of his body, such as; The nose, ears, thighs, and shoulders, and this is due to the fact that these parts are often free of fur or have blood vessels close to the skin, and swimming also enables him to get rid of excess heat.

Can a polar bear live in a warm environment? 

Biologists have pointed out that the polar bear is unlikely to live in a warm environment. They also note that global warming is making the polar bear lose its habitat and cold natural environment; Which will cause it to move to the south in search of food, thus competing with the grizzly bear breed in its environment.
