toothed whalenounA predatory whale having teeth rather than baleen plates. Toothed whales include sperm whales, killer whales, beaked whales, narwhals, dolphins, and porpoises.- Suborder Odontoceti, order Cetacea: six families and numerous species.
Odontocete cetaceans (i.e., toothed whales including dolphins and porpoises) rely upon echolocation to sense the environment and detect prey....- Some baleen whales, most famously the humpback whales, are known for the strange and complex songs they produce; their function is not clear, but unlike toothed whales, baleen whales do not use their songs for echolocation.
- This anatomical quirk occurs only in toothed whales - including the sperm whale, narwhal, orca, and porpoise - and it helps explain an old maritime mystery.
