Answer 2

A thick layer made of fats is present below the skin of the animals which stays in regions which is very cold. This layer is called Blubber.

This layer is present to help the animals to be warm and escape from the extreme coldness. The adipose tissue which makes up this layer has low heat conductivity. Due to this property, no heat is transferred to other tissues. Thus, it performs its duty by insulating the body of the animals.
