The story of the word

The other half of the order is the baleen whales, who traded teeth for a filter. Every odontocete has a single blowhole and a fatty melon in the forehead that focuses its clicks. Kētos gave Latin cetus and the constellation Cetus, and also the name Keto, the sea goddess whose children in Hesiod include the Gorgons.
