Stejneger's beaked whale has the characteristic Mesoplodon body shape. Apparently, both sexes are uniformly grey to black, often with extensive scarring in bulls. The flattened tusks of males are situated near the middle of the lower jaw, and point forward. They are located on raised prominences, so that the crowns extend above the rostrum. Can be confused with: Adult males will be distinguishable from most other Mesoplodon species by tooth shape and position. Within Stejneger's beaked whale's range, both Hubbs' beaked whale and Blainville's beaked whale males have similar teeth.
