Information on the geographic range of this species is limited due to its rarity. Based on stranding and fishery by-catch records, dwarf sperm whales have a worldwide distribution. Although stranding records show that they occur in areas of cold waters, they are more frequently observed in temperate and tropical regions. In the Atlantic Ocean, dwarf sperm whales have been spotted offshore near Virginia, Spain, Brazil, and along the coasts of Africa. In the Indian Ocean, strandings have occurred along the southern coast of Australia, in the Persian Gulf, and in the Indonesian archipelago. In the western Pacific, strandings have occurred along the shores of the island of Honshu in Japan, the Marianas Islands, and New Zealand.

Kogia sima — Dwarf Sperm Whale
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 tail in the other.
