Detailed explanation-1: -Blubber is a thick layer of fat, also called adipose tissue, directly under the skin of all marine mammals. Blubber covers the entire body of animals such as seals, whales, and walruses-except for their fins, flippers, and flukes.

Detailed explanation-2: -Blubber is a specialized subcutaneous layer of fat found only in marine mammals and is different from other types of adipose tissue in that it is anatomically and biochemically adapted to serve as an efficient and adjustable thermal insulator.

Detailed explanation-3: -Blubber is important for most marine mammals, such as whales and seals. The thick layer of fat provides insulation from cold ocean temperatures.

Detailed explanation-4: -Two kinds of oil came from whales: oil rendered from the blubber, and the higher-grade spermaceti. All whales have a thick layer of blubber that keeps their body temperature regulated as they travel through cold water; at a high enough temperature this blubber can be rendered into oil.

Detailed explanation-5: -Blubber is a thick layer of fat (adipose) tissue. Animals store extra digested food in the form of adipose tissue, which contains molecules called lipids. Adipose tissue has a relatively low thermal conductivity, which means that it does not transfer heat as well as other tissues and materials-such as muscle or skin.
