Whippomorpha^[1] is a proposed clade containing the Cetacea (whales, dolphins, etc.) and their closest living relatives, the hippopotamuses defined by Waddell et al. (1999). It's defined as a node-based taxon, including all species that are descendants of the most recent common ancestor of Hippopotamus amphibius and Tursiops truncatus.^[2] This would be a sub-grouping of the Cetartiodactyla (which also includes pigs and ruminants), but 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.^[3]

Whippomorpha is a mixture of English (wh[ale] + hippo[potamus]) and Greek (morphe = form). Attempts have been made to rename the clade Cetancodonta but Whippomorpha maintains precedent.^[4][5]
