Included in Arctocephalus by Van Gelder (1977b). Mohr (1952) reported successful matings between Arctocephalus pusillus and Z. californianus. Rice (1998), followed here, argued for the retention of japonicus, californianus, and wollenbaeki as distinct species. Itoo (1985) concluded that japonicus was distinct, and behavioral differences separate californianus and wollenbaeki (Eibl-Eibesfeldt, 1984). But see Scheffer (1958) who recognized these populations at the subspecies level.
