What are 3 physical adaptations of a polar bear?

Their adaptations include:

• a white appearance – as camouflage from prey on the snow and ice.
• thick layers of fat and fur – for insulation against the cold.
• a small surface area to volume ratio – to minimise heat loss.
• a greasy coat that sheds water after swimming – to help reduce heat loss.

What are two physical adaptations of a polar bear?

What are the adaptations of a polar bear to survive?

Polar bears live in one of the planet’s coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice.

What behavioral adaptations do polar bears have?

Sleeping behavior. They also frequently nap to conserve energy. The bears typically curl up and dig shallow pits in the snow, sleeping with their backs to the wind. For comfort, the bear uses one of its outstretched paws as a pillow and allows snow to pile up around it to provide extra warmth and insulation.

What are physical and behavioral adaptations of a polar bear?
