Adaptation, Polar Bear.

Extracts from this document...



Food, Eating and Hunting

The Polar Bear mainly eats seals, except in the summer when they eat vegetation and berries. They are called omnivores, which means that they eat plants besides meat.

When the Polar Bear hunts a seal he stays low to the ground and creeps quietly toward it. Even though Polar Bears usually do not like to swim, they probably will to catch a seal. Sometimes if a Polar Bear want to blend in with the snow even more when hunting, they will put their paw over their nose and lips so the seal won’t see them.

After they kill the seal by hitting it and strangling it, they will only eat the fat and skin, leaving the meat behind for scavengers like foxes and birds. Sometimes they come together to eat but they usually eat alone. Polar Bears travel many miles in search of food.

Polar Bears have two layers of fur over a thick layer of fat. Their coat is warm and waterproof. Sometimes they will even lie down on the snow to let heat escape from their body. Their skin is black under their white fur, which is good camouflage against the snow, for when they hunt. Polar bears also don't have any eyelashes because they would freeze in the cold.

Polar bears can walk on the ice without slipping, because of the fur in between their toes. When they walk their front paws turn inward and they usually don't run.

The polar bear is the largest bear in the world. Polar bears are full-grown at about five or six years of age and they stay with their mothers for about two and a half years. When the cubs are born they are blind, hairless and no bigger than a guinea pig. The largest polar bear ever seen was eleven feet standing. Their shoulder height is five feet.

Grow your toenails until they work like hooks!
Polar bears have long, curved claws that are as sharp as nails, which help them cling to slippery ice when they walk or run.

Add a thick layer of blubber to your body.
Polar bears aren't actually overweight, but they do have up to five inches of fat, called blubber, under their skin. This blubber keeps them warm. It also serves as stored energy to help polar bears get through the winter, when food is scarce

Perfect your sense of smell.
Polar bears have an outstanding sense of smell. They can smell seals, their favourite food, from as far as ten miles away! When there isn't many food closes by, polar bears' nose help them hunt for dinner

Blend into the snow.
Polar bears are white - the same colours as the snow and ice around them. Because they blend into their surroundings so well, polar bears can sneak up on their prey without being spotted.
Polar bears are perfectly suited to life in the freezing Arctic.
