Feature and Habit |
---|
Stejneger's beaked whales have small head beak. The dorsal fin is small and locates quite posterior in position. The flipper is also small. The body color of newborns is almost brown and white ventrally, as they grow up, they become gray-blue to dark gray. Adult males have scratches believed to be caused by intraspecific fighting among adult males in breeding season. Only in adult males a pair of the teeth erupt in the lower jaw. This prominent tooth-like tusk is visible beside the upper jaw. They strand at various localities along the Sea of Japan coasts during the season early winter to early summer. |
