Polar bears have several adaptations that help them survive in Arctic conditions, including transparent white fur that camouflages them in snow, black skin that absorbs heat from the sun, broad paws that spread their weight on ice and aid swimming, curved claws for digging in ice, small ears and tails to minimize heat loss, and a thick layer of fat that insulates them. They are skilled hunters both on land and sea, patiently waiting at seal breathing holes and swiftly attacking when seals emerge or swimming to ambush seals resting on ice. Their diet consists of seals, small whales, walruses, sea birds and eggs, and they will also scavenge dead animals.

4. WHITE FUR: actually transparent, for camouflage in ice and snow.SKIN: their skin is black to absorb heat from the sun's rays to help keep them warm.PAWS : the pads provide traction on ice.BIG PAWS : spread body weight on ice, and are broad for use in swimming.

5. CLAWS : are curved to dig through ice.SMALL EARS and TAILS : are short to minimize heat loss.TEETH : more jagged than most bears, suiting a carnivore.FAT LAYERS: keeps them warm (insulates).NOSTRILS : their nostrils close underwater.
When they close it
they can swim

6. How they hunt their food.
They are excellent hunters from both land and sea.
aseal´s breathing hole
• They are excellent hunters from both land and sea. Patiently waiting
near aseal's breathing hole, they bite the head with their sharp teeth
when the seal emerges. Submerged they will swim towards an exit in
the surface, suddenly surface, and attack any seal resting nearby. In
captivity they eat whatever diet is prepared for them.

7. They eat small
whales like
the beluga
They also
eat walrus
Polar bears will eat sea birds and their eggs if
available where they live. Their eating habits include
scavenging for dead animals including different types of
whales and fish. The polar bear is an important part of
Arctic food chain.
