Gervais' beaked whale is a member of the beaked-whale family that lives in deep Atlantic waters. It is rarely seen at sea and is usually alone or in small, closely associated groups.
Its body is dark gray to bluish black, with a paler underside, a long beak and a sloping forehead. Mature males have a pair of exposed lower-jaw teeth; females and juveniles also have teeth, but they remain under the gums.
It dives deep and uses suction to feed mainly on cephalopods such as squid, along with mysid shrimp and small fish. Its low profile and inconspicuous surface blow make it difficult to observe, so much of its behavior is poorly known.
