Size: The size of Longman's beaked whale is unknown, but based on the size of a skull it is thought to reach lengths of over 6 m.

Nothing is known of the external appearance of Longman's beaked whale, as it is known only from 2 damaged skulls. The teeth of adult males are oval in cross-section, are located at the tip of the lower jaw, and point forward.

Can be confused with: Until a fresh carcass is examined, Longman's beaked whales cannot be positively identified (except from examination of the skull). In shape and position, the teeth most closely resemble those of True's beaked whales.
