  • 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.

How do polar bears adapt to climate change?

However, unlike their grizzly ancestors, polar bears are not equipped to survive solely on land. They need the ice—and the blubber-rich animals that congregate there—to survive.

Which adaptation helps polar bears maintain a constant internal temperature in cold weather?

Thermoregulation. Body temperature, which is normally 37°C (98.6°F), is maintained through a thick layer of fur, a tough hide, and an insulating fat layer (up to 11 cm or 4.5 in. thick).

What are some behavioral adaptations of a polar bear?
