Gervais' beaked whale  (Mesoplodon europaeus)

Gervais' beaked whale has a prominent, slender beak with only two teeth which, whilst obvious in males, are not visible in females (5). These whales are dark grey to black on the back, fading to light grey or white on the underside. The head is relatively small with a slightly bulging forehead and the dorsal fin is situated towards the tail end of the back (2) (5).
