How do animals survive in extremely cold habitats?

Animals survive in extremely cold habitats through adaptations that help them maintain body temperature, find food, and protect themselves from harsh conditions. These adaptations may include special body structures and behaviours.

Many cold-region animals have thick fur, feathers, or layers of fat under their skin that reduce heat loss and keep their bodies warm. For example, polar bears have thick fur and a fat layer that help them survive freezing temperatures. Some animals migrate to warmer areas or reduce their activity during extremely cold periods.

These adaptations allow animals to live in habitats with low temperatures, snow, and limited food availability.
