Although the two subfamilies of otariids, the Otariinae (sea lions) and Arctocephalinae (fur seals) are still widely used, recent molecular studies have demonstrated they may be invalid. Instead, they suggest three clades within the family, one consisting of the northern sea lions (Eumetopias and Zalophus), one of the northern fur seal and its extinct relatives (Callorhinus), and the third of all the remaining, Southern Hemisphere, species.
