Question

what are the adaptive features of animals which are seen in colder regions ?

Answer 1

Some adaptive features of animals in colder areas are:
1. They burrow themselves in the snow. Snow acts as an excellent insulator by trapping air.
2. Some animals hang out in groups which provide them with warmth and protection. E.g. Arctic Hares.
3. Hibernation is an adaptive feature of many to escape the cold.
4. Presence of fur insulates their body.
