| Thirty-one of the 48 sightings of Stejnegers beaked whale have come from Alaskan waters. It is suspected this species favors deep waters, including the Aleutian Trench and the Aleutian Basin, which is some 3,500 m deep, rather than the shallow waters of the Bering Sea. The whales were seen traveling in groups of 5-15; some individuals were large and some were small. This species is also known as the sabre-toothed beaked whale, hinting at the shape of the adult male's teeth.
