Polar Bear

Polar Bear Polar Bear (Ursus maritimus) is the largest species of the bear family. These species are also known as white bear. The males of these species are larger than the females. The males of these species weigh about (300 to 600) kg and measure up to (2.4 to 3) meter in length, whereas the females weigh about (150 to 300) kg and measure up to (1.9 to 2.1) meter in length. They have a black nose, small head and powerful jaws. Their sense of smell is very strong. These bears have a flat and small tail and also have around 42 teeth. The webbed toes of these species help them to swim. They paddle with their front feet and use their hind feet to steer. These creatures live on the coldest environments of this planet and so they have been provided with a thick coat of insulated fur. These furs can be seen even on their paws, which protect them from the cold temperature. These species are white and their color provides camouflage when they are between ice and snow. The skin of these species, which is under their furs, is black and it absorbs sun's rays up to a great extent.

Diet
The favorite food of these species is seals. They like to eat mostly the ringed seal, which is their most favorite food. These bears sometimes also feed on sea birds, eggs, mammals, small whales and walrus. These species are known to be very good hunters both on the land and the sea. They wait patiently near the holes of the seals and when the seals come out they bite them on their head with their sharp teeth. Apart from this they swim near the surface and attack on a seal resting nearby. These species do not drink water because they get their liquid from the food, which they eat.

Habitat
These bears are found in the Arctic areas of Norway, Russia, Greenland, Canada and Alaska. They are known to cover long distances even on the land. These creatures are very good swimmers and can swim up to a speed of 6 mile per hour in the water. These species are also a very good diver and the hunters feel very difficult to catch these sea animals. These sea creatures spend most of their time in the Arctic Ocean just searching and hunting for food.

Reproduction
These bears reach maturity at the age of about (3 to 5) years. The breeding generally takes place in the month of April. The male can travel a long distance in the search of a female to mate. The pregnant females dig out dens in order to give birth to their young ones. The females of these species give birth to the two cubs in the month of December or January. The temperature of the den is around 40 degrees more compared to the temperature outside. The cubs are blind, small and hairless at the time of birth but grow rapidly from the milk of their mother.
