The dwarf sperm whale (Kogia sima) is a sperm whale that inhabits temperate and tropical oceans worldwide, in particular continental shelves and slopes. It was first described by biologist Richard Owen in 1866, based on illustrations by naturalist Sir Walter Elliot .
Kogiidae is a family comprising at least two extant species of Cetacea, the pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales.As their common names suggest, they somewhat resemble sperm whales, with squared heads and small lower jaws, but are much smaller, with much shorter skulls and more notable dorsal fins than sperm whales.

Kogia is a genus of toothed whales within the superfamily Physeteroidea comprising two extant and two extinct species from the Neogene: Pygmy sperm whale, Kogia breviceps; Dwarf sperm whale, Kogia sima †Kogia pusilla, Italy, Middle Pliocene †Kogia danomurai Pisco Formation, Peru, latest Miocene
The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the largest known animal that has ever lived. The sperm whale is the largest toothed predator on Earth.

They have also been reported to eat some deep-sea shrimps, but, compared with dwarf sperm whales, relatively few fish. [9] Predators may include great white sharks [28] and killer whales. [29] Pygmy sperm whales and dwarf sperm whales are unique among cetaceans in using a form of "ink" to evade predation in a manner similar to squid.
