Whales and other sea mammals have a thick layer of fat in their bodies called blubber which helps the whales and is the cause that whalers hunt whales. The blubber is used to keep the whale warm, and when the whale is in the breeding grounds, he can't eat, so he has to live off the blubber he has saved up. They are important to humans, too. They were used for oil lamps, oil machines, make expensive perfume, etc...
