Blubber an essential component of a marine mammal's shape. It stores power, isolates heat, and enhances buoyancy.
Energy is collected in the solid, oily coating of blubber. The heat stored in blubber involves both proteins and fats. The capability of blubber to utilize these collected nutrients involves marine mammals are not attacked to hunt for meat for a prolonged period of time.
Blubber also covers marine mammals or assists to keep them heated in icy sea waters. This padding is required.
