Where the name “Polar bear” comes from
Its scientific name Ursus maritimus means maritime bear.
University of Michigan Animal Diversity WebIts head is small compared with its body and its front paws are big, giving it a body suited to swimming; it is good at diving, too.
It hunts on the ice too, lying in wait for seals or attacking seals that are raising their young in holes in the ice.
How the Polar bear lives
After eating, they wash by licking and rinsing their fur. They spend much of their time sleeping or lying down. A female close to giving birth digs a den in the snow and gives birth inside it.
