True's beaked whales are mottled dark-grey on their back, with a dark patch around the eye. The body is scarred and the rear third of the body is often pale. They have a slightly bulging forehead, a medium-sized beak, and small teeth on the lower jaw.
True's beaked whales inhabit temperate seas of the North Atlantic and South Africa.
They feed on squid.
Little is known about their behaviour, but the fact that the males are often scarred suggests that aggression occurs between them.
True's beaked whales are classified as Data Deficient by the 2000 Red List.
