The number of species within the genus has been questioned, primarily based on limited molecular data. The issue is complicated by the fact some of the species are able to produce fertile hybrids. A recent review recommended the retention of seven species, deprecating the New Zealand fur seals to a subspecies of the South American fur seal, while also questioning the status of the Guadelupe fur seal. Other recent studies have indicated that the genus may be paraphyletic, in which case, all species except for the Cape fur seal may have to be split off into a separate genus.
