Long Cetartiodactyla
Whales are a diverse and broadly distributed group of fully marine placental marine mammals. They are an unofficial suborder of the Cetacea, typically excluding dolphins and porpoises. Whales, dolphins, and porpoises are members of the order Cetartiodactyla, which includes even-toed ungulates. Their nearest living relatives are hippopotamuses, from whom they separated about 40 million years ago.
