Environment/Habitat
Kogia breviceps is rarely seen at sea; it tends to live a long distance from shore and has inconspicuous habits. According to Caldwell and Caldwell (1989) K. breviceps lives in oceanic waters beyond the edge of the continental shelf while K. sima lives over or near the edge of the shelf.

Morphology/Character
Like its giant cousin, the sperm whale, the pygmy sperm whale has a spermaceti organ in its forehead (see Sperm Whale for a discussion of its purpose). It also has a sac in its intestines that contains a dark red fluid. The whale will expel this fluid when frightened. Its purpose is believed to be to confuse and disorient predators. The Pygmy Sperm is amongst the smallest of all whales and is not much larger than many dolphins. The underside is a creamy, occasionally pinkish, colour and the back and sides are a bluish grey; there is, however, considerable intermixing between the two colours. The head is large in comparison to body size, given an almost swollen appearance when viewed from the side. The lower jaw is very small and slung low. The blowhole is displaced slightly to the left when viewed from above facing forward. The dorsal fin is very small and hooked; its size is considerably smaller than the Dwarf Sperm Whale's and may be used for diagnostic purposes. This whale makes very inconspicuous movements. It rises to the surface slowly, with little splash or blow, and will remain there motionless for some time.
