Sato's beaked whale (Berardius minimus) is a little-known species of four-toothed whale.[2]

Description[]

Sato’s beaked whale is one of the poorly distinguished species in the genus Berardius. It was distinguished from Arnoux's and Baird's beaked whale in 2019 on the basis of mtDNA differences.[3] It generally has a short beak (~4% body length). While other four-toothed whales are generally grey with scars, kurotsuchis usually have few linear scars, so that the dark, smooth skin contrasts highly with round, white scars of about 5 cm diameter (from cookiecutter shark bites).[citation needed]

Distribution[]

The species' distribution, based on genetic samples from strandings only, is believed to include the sea around Japan, the Russian Federation, and Alaska.[1]

Conservation[]

Although very little is known about the ecology and populations of Sato's beaked whale, the IUCN has assigned the species a classification of Near threatened based on its estimated low population numbers.[1]
