Apparently limited to the North Pacific Ocean, Hubbs' beaked whale is known from central British Columbia to southern California in the east, and from Japan (including the Sea of Japan) in the west (Mead 1989; MacLeod et al. 2006). Although the vast majority of records are of strandings, sightings have been made off the coast of Oregon and Washington (Mead et al. 1982, Heyning 1984). This is an oceanic species, and the range is thought to be continuous across the North Pacific, although this is not confirmed (MacLeod et al. 2006).
