Two types ofBerardiusare recognised by local whalers in Hokkaido, Japan. The first is the ordinary Baird’s beaked whale,B.bairdii, whereas the other is much smaller and entirely black. Previous molecular phylogenetic analyses revealed that the black type is one recognisable taxonomic unit within theBerardiusclade but is distinct from the two knownBerardiusspecies. To determine the characteristics of the black type, we summarised external morphology and skull osteometric data obtained from four individuals, which included three individuals from Hokkaido and one additional individual from the United States National Museum of Natural History collection. The whales differed from all of their congeners by having the following unique characters: a substantially smaller body size of physically mature individuals, proportionately shorter beak, and darker body colour. Thus, we conclude that the whales are a thirdBerardiusspecies.
