beaked whales takes their name because of the shape
of the male's teeth. They are very similar to the shape
of the Ginkgo tree which is common in Japan, where this
whale was first found. These teeth are 10cm wide which
makes them the widest teeth in any known beaked whale.
Males are dark in colour with white spots and blotches
around the belly area. Females are not as dark and have
paler bellies. They have narrow upper jaws with a sharp
point and their lower jaws are highly arched. Their
flippers and fins are small and narrow. Unlike many
of the other beaked whales Ginkgo-toothed beaked whales
are not usually scarred.
