This whale is 1 of 3 species of sperm whale; the other two are the sperm whale and the dwarf sperm whale. To assist with swimming these whales have a pair of flippers to help them turn and steer in the water and rear flukes which they move up and down to propel themselves forward. In terms of dentition these whales may have anywhere from 10 — 16 teeth in their lower jaw, but lack having any in their upper jaw. Whether or not their teeth are necessary for hunting prey is uncertain as their larger sperm whale relative is known to successfully capture prey without teeth and even with a deformed jaw.

The pygmy sperm whale Kogia breviceps is one of three species in the family Kogiidae in the sperm whale superfamily.

The pygmy sperm whales was first described by naturalist Henri Marie Ducrotay de Blainville in
