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]
