Enhydriodon dikikae
"Enhydriodon dikikae" belongs to the Carnivora order, Musteloidea superfamily, Mustelidae family and Lutrinae subfamily. The closest living relative to this species is the modern otter. Other related animals in the Musteloidea superfamily are from the family, Procyonidae to which animals like racoons, olingos and coatis belong to. There is some debate over whether "E. dikikae" should belong to the "Sivaonyx" genus however at this point, it is still classified as being in the "Enhydriodon" genus.
