Range: Phocoenoides dalli occurs in the northern East Sea (north from 35? latitude; Fig. 110). The distribution moves closer to the east coast of Korea during winter (Kim 2004).

Remarks: A controversy exists on whether the two well-defined co-occurring color morphs forms ‘ dalli’ and ‘ truei’ represent distinct species, subspecies or color morphs (Escorza-Trevino et al. 2004).
