Short note :Adaptations of mammals in colder regions.

1.	Short note :Adaptations of mammals in colder regions.
Answer» 1. Mammals inhabiting colder regions have shorter snout, ears, tail and limbs to minimize the loss of body heat. This is called Allen’s Rule. 2. Aquatic mammals such as whales and seals living in the polar seas, have a thick layer of fat which is called a blubber below their skin. 3. Blubber acts as an insulator and thus helps to keep the body warm by reducing loss of body heat. 4. Some animals like polar bears undergo hibernation and thus tide over the stressful winters.
