Taxonomy
Kingdom:Animalia
Phylum:Chordata
Class: Mammalia
Order:Cetartiodactyla
Family:Ziphiidae

Description
Size: At birth: 2.7 m; adult: 7.5 m.

Weight: Male: 5.6 tons; Female: 6.5 tons.

Color: Body coloration is variable between the individuals, the back being dark rust brown, slate-grey or fawn colored. The belly is usually lighter. The head, especially in older males, is paler and almost completely white or cream-colored oval blotches on the belly and sides.

The body of this beaked whale is long and robust, with a small head. The forehead slopes gradually, so that the short beak is not sharply defined. The scooped appearance of the head, and the shape, light color and relatively small size of its rostrum give it the name Goosebeak Whale. The lower jaw extends beyond the upper one.

A V-shaped pair of throat grooves, characteristic of beaked whale is present. The flippers are small, and the high dorsal fin may be sickle-shaped or triangular. The rear margin of the flukes is slightly concave. A single pair of conical teeth is present at the tip of the lower jaw. These are large in males, but in females they are slender and pointed, and do not normally erupt. The species has a low and inconspicuous spout, which projects slightly forward and to the left.

Cuvier’s Beaked Whales make deep dives lasting up to 30 minutes to find prey. Cuvier’s Beaked Whale is one of the commoner beaked whales. It was first described by Georges Cuvier from a skull found in Marseilles in 1804. This species normally lives in extended family pods of around 15 individuals. Solitary males are sometimes seen. They seem to strand more often than the other beaked whales.

Similar species: This species may be confused with other Beaked Whales, but their robust body, blunt head and lighter coloration around the head is diagnostic.
