Detailed explanation-1: -The thick layer of fat found in polar bears, penguins, whales, seals and dolphins which helps to protect against the cold and also aid in buoyancy is called blubber. Blubber is found just below the skin and is widely used in the Arctic region as a source of fat. Blubber is also used to make oils.

Detailed explanation-2: -Underneath their fur, polar bears have black skin which absorbs the heat of the sun, and below the skin is a thick, 4-inch layer of blubber. This blubber layer is particularly beneficial while polar bears swim, keeping them warm in the cold water and increasing buoyancy.

Detailed explanation-3: -Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic.

Detailed explanation-4: -They have a thick layer of body fat, which keeps them warm while swimming, and a double-layered coat that insulates them from the cold Arctic air.

Detailed explanation-5: -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. Blubber an important part of a marine mammal’s anatomy.
