of the earth’s largest and most powerful carnivores, the
polar bear is found in all the world’s arctic seas and
coastal lines. In appearance, it differs from other bears
in its longer neck, long narrow head and longer legs.
The polar bear may surpass the Alaskan grizzly in size,
with the maximum recorded weighing 726 kg.
They are the most carnivorous of the bears, and their
favourite prey are seals and young walrus. In addition
to their mainly meat diet, they graze on grasses, mushrooms,
and berries. When disturbed, it heads for open water at
a rolling gallop at a top speed of about 40 km/h. They
have, aside from humans, no natural enemies, but they
occasionally fall victim to killer whales.
