These are found in most of the planet’s oceans, and perhaps in a few freshwater rivers. Inspite of their quite different eating plans and sizes, equally baleen whales (Mysticeti) and toothed whales (Odontoceti) share a standard (and perhaps astonishing) ancestor—land-dwelling mammals linked to now’s hippos that lived above fifty million a long time back.
