Blubber is a thick layer of fat found beneath the skin of marine mammals such as whales, seals, and polar bears. It serves as an insulating layer that helps these animals regulate their body temperature in cold environments. In polar bears, for example, blubber can be up to 10cm thick and is covered with a layer of fur, providing a highly effective means of insulation against the cold Arctic winters.
