Blubber

As Blubber (of English blubber. Blubber, fish oil ) is called the several centimeters thick layer of fat of whales and seals.

Mammals are the same cold-blooded animals. That is, they keep their body temperature constant. Since water has a higher density than air, the body heat of marine mammals is transported faster than that of the living land mammals. Therefore, the need to protect marine mammals, particularly from hypothermia. Equal Warm land animals protect themselves with fur, which forms an insulating layer of air acting to the animal. Underwater isolated fur is not enough, therefore, need marine mammals a thick layer of fatty tissue to protect themselves from the cold. In species that live in cold waters, this layer can be more than 50 cm thick. With a Blue Whale Blubber of up to 50 tonnes.

From the Blubber earlier Tran was recovered.
