Strap-toothed Beaked Whale

The Strap-toothed Beaked Whale is rarely seen, as this is an open-ocean species. It can be identified by its small melon shaped head which has a grey band behind and joins with a light grey band on the dorsal surface. Smaller than Cuviers Beaked Whales, Strap-toothed Beaked Whales reach about 6 m in length and weigh up to 2 ton. Males have a pair of long, strap-shaped teeth (tusks) in the lower jaw that prevent them fully opening their mouths as they curl backward and inward. They are known to bask on calm, sunny days and sink slowly below the surface. They do not generally show their flukes on diving, which lasts at least 10 minutes. They are generally black/grey in colour, some with a brownish tinge and white underside. They have a white throat-patch which extends behind the eye and blends with a lighter grey on the dorsal surface. In other characteristics they are similar to other beaked whales with a slender body and long dolphin-like beak, triangular tail fluke and small sickle-shaped dorsal fin.
