This animal has never been observed alive and is only known from less than half a dozen strandings. They are easily confused with Hector’s and Cuvier’s beaked whales for the similarities are remarkable, and it is most closely related to the pygmy beaked whale. Only DNA evidence classifies this animal, named after cetologist Dr. William F. Perrin, as a distinct species.
