According to recent work, Carnivora is divided into Feliformes (which
contains cats, hyaenas, vivverids, mongooses [mongeese?]) and Caniformes
(which contains dogs and the arcotoids: mustelids, racoons, red pandas,
bears, and pinnipeds. Bears are, in this scheme, the closest living
relatives of the Pinnidpedia, although some have argued for a diphyletic
seal group, arising twice within the Arctoidea).
