Hawaii’s confirmed sightings of Blainville’s beaked whale come from far offshore, in the deep water beyond the main Hawaiian Islands’ fringing reefs, including the channels between Maui, Lānaʻi, and the Big Island where the seafloor drops away fast. It’s a species built for open, deep water, not the shallow leeward coasts where most whale-watching happens.
Males carry two tusk-like teeth erupting from an arched lower jaw so dense the species is named for it, densirostris, Latin for dense beak. It dives deep and stays down a long time hunting squid, surfacing only briefly, which is exactly why a live sighting anywhere, including Hawaii, stays rare even where the whale is reliably recorded.
Nearly all of Hawaii’s reports land in February, with only a handful scattered across the rest of the year. That sharp seasonal spike likely reflects when surveys and boaters are out looking, not a real migration into state waters.
