As the largest land predators alive in the world as of 2014, most adult polars bears in the wild weigh between 900 and 1600 pounds and are from 7.25 to 8 feet long. Females are smaller than males, even in the later stages of gestation.
Despite their enormous size, polar bears are excellent swimmers, using their large front paws as paddles. Aided by a warming layer of fat and a thick layer of insulated fur, the Arctic bears are able to survive the planet's coldest environments. Black fur under their white coat also allows them to absorb the sun's rays better, while their white coat blends with the snow and ice to help them sneak up on prey.
