The Pygmy sperm whale (Kogia breviceps) is not often sighted at sea, and most of what is known about this species has come from the examination of stranded specimens. There were 27 pygmy sperm whales reported stranded on New Zealand beaches between 1991 and 2003.
The pygmy sperm whale is not much larger than many dolphins. They are about 1.2 m at birth, growing to about 3.5 m at maturity. Adults weigh about 400 kg. The underside is a creamy, occasionally pinkish colour and the back and sides are a bluish grey; however, considerable intermixing occurs between the two colours. The shark-like head is large in comparison to body size, given an almost swollen appearance when viewed from the side. A whitish marking often described as a "false gill", is seen behind each eye.
The pygmy sperm whale has a "melon", a body of fat and wax in the head that it uses to focus and modulate the sounds it makes. 
The Pygmy sperm whale has between 12-16 sharp, curved pairs teeth in their lower jaws. These teeth fit into pockets in their upper jaw. They feed on octopuses, squid, crab, fish, and shrimp.
