Gervais' beaked whale Mesoplodon europaeus is a toothed whale and can be recognised as such by the single blowhole and the presence of teeth (rather than baleen). It is a member of the beaked whale family with the characteristic V-shaped crease on the throat and the short dorsal fin set relatively far back. Gervais' beaked whale is a small beaked whale that can reach up to 5.5 m in length. The lower jaw has a single pair of teeth (exposed only in adult males). The forehead rises at a shallow angle. It has a distinct beak and the mouthline is curved down at rear. Gervais' beaked whale has a charcoal grey dorsal and lateral colouration with a lighter belly. Adults may have clear scratches and scars on the body.Gervais' beaked whale may be confused with True's beaked whale Mesoplodon mirus but it has conspicuously smaller flippers. Gervais' beaked whales are usually found either alone or in small groups. Very little is known about their behaviour and dive duration due to the relative lack of sightings (Kinze, 2002).
