Cuvier's beaked whale surface characteristics


Cuvier's Beaked Whale | Cetacean Fact Sheet | American Cetacean Society

Cuvier's beaked whale has a robust body and a small head which is about ten percent of its body length. Its forehead slopes to a poorly defined short beak, and its mouth turns upward, giving it a goose-like profile. This whale has a depression behind the blowholes which ends in a distinct neck. Its blow is small and not very noticeable and is projected slightly forward and to the left. One of its more interesting features is that in adult males two large teeth about 2 inches long (5 cm) protrude from the tip of the lower jaw. The males use these teeth in fights with each other over females. For their part the females have smaller, more pointed teeth that remain embedded in the gums. The lower jaw of the Cuvier's beaked whale extends well beyond the upper jaw. Like other beaked whales, the Cuvier's has two deep, V-shaped throat grooves.
COLOR:
This whale varies greatly in color. Its back may be rusty-brown, dark gray, or fawn colored and the underside of the body may be dark brown or black. As the Cuvier's beaked whale ages, first the head and neck and then the body become more lightly colored; the heads of old males are almost completely white. The back and sides of this whale, especially the males, are often covered with double-lined scratches caused by the teeth of other males. Its sides and belly are covered with oval white patches.
