A whaler is a person who hunts whales, or the boat they use. They hunt whales for their oil, made from their fat, called blubber, and the meat. Today, there is a treaty which bans the hunt of some whale species. Most countries signed the treaty. A few countries still hunt whales for research purposes. Among those countries are Norway, Iceland and Japan.
