This beaked whale is recorded in deep waters of the North Pacific. At-sea sightings are rare, so much about its appearance and behavior remains uncertain.
Juveniles genetically identified as this species off Oregon had gray bodies with dark markings around the eyes. The head narrows into a beak-like rostrum.
Two juveniles observed off Oregon stayed near a research vessel while scientists recorded photographs, sounds, and behavior. This is one rare at-sea observation.
An extinction-risk assessment has not been added yet.
