Whales are divided into two groups. The baleen or whalebone whales have no teeth, only a flexible horny substance called baleen, which looks like a sieve or strainer, suspended from the upper jaw. There are 10 baleen whale species, including most of the enormous whales. The other group is the toothed whales. This group has 66 species and includes sperm whales, killer whales, dolphins, and porpoises. The minke whale is a baleen whale.
