meaning for a pupil

(science) Any member of the group of sea mammals that includes whales, dolphins and porpoises. tree →

sense in the lessons

In science lessons, cetaceans are mammals, not fish: they breathe air through a blowhole, are warm-blooded, give birth to live young and feed them milk. Some (baleen whales) filter tiny food through baleen plates; others (toothed whales, dolphins) have teeth. In the Just So Story «How the Whale Got His Throat», Kipling jokes that the Whale's throat was blocked by a grating made from a raft, so he can only eat very small fish — real baleen whales do eat tiny krill, but not because of a grating.
