1.3.3 The order Cetacea
The cetaceans get their name from the Greek word ‘ketos’ meaning ‘whale’. The order is divided into two suborders: the Odontoceti, or toothed whales, which include the sperm whale, killer whale, dolphins and porpoises; and the Mysticeti, or baleen whales, which include the blue whale, right whale and humpback whale, and are named for the brush-like plates that they use to filter krill from the water.
