Whippomorpha (also known as Cetancodonta) is a whimsical name for the clade containing the Cetacea (whales, dolphins, etc.) and their closest living relatives, the hippopotamuses. This would be a sub-grouping of the Cetartiodactyla, which also includes pigs and ruminants. It is not clear how recently the whales and hippos share a common ancestor, though the genetic evidence is strong that the cetaceans arose from within the Artiodactyla, thus making the even-toed ungulate classification a phenetic one.[1]

Cetancodonta is the clade containing the Cetacea (whales, dolphins, etc.) and their closest living relatives, the hippopotamuses. This would be a sub-grouping of the Cetartiodactyla, which also includes pigs and ruminants. It is not clear how recently the whales and hippos share a common ancestor, though the genetic evidence is strong that the cetaceans arose from within the Artiodactyla, thus making the even-toed ungulate grouping a paraphyletic one.[1]

The Cetancodonta have also been referred to as "Whippomorpha", the "Whippo-" element being a portmanteau of whale and hippo.
