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 , based on illustrations by naturalist Sir Walter Elliot. The species was considered to be synonymous with the pygmy sperm whale Kogia breviceps from until The dwarf sperm whale is a small whale, 2 to 2. Its appearance is very similar to the pygmy sperm whale, distinguished mainly by the position of the dorsal fin on the body—nearer the middle in the dwarf sperm whale and nearer the back in the other. The dwarf sperm whale is a suction feeder that mainly eats squid, and does this in small pods of typically 1 to 4 members.

It turned out to be one of the Kogia species which include the Pygmy Kogia breviceps and Dwarf Kogia sima Sperm whales. Until all kogia were seen as one species, but were later separated into two distinct species due to genetic and morphological differences. In recent years studies on Kogia sima further shown genetic differences between the Atlantic and the Indo-Pacific ocean, but more information is needed to categorize and give them different species status. To spot a Kogia at sea is hard, if not impossible, unless the sea is extremely calm.
