Mesoplodon

Mesoplodon is a genus of small-toothed whales, commonly known as beaked whales. These marine mammals are found in oceans worldwide and are characterized by an extended snout and two throat grooves that meet under the chin.12

Beaked whales vary in size, with lengths ranging from approximately 3.7 to 13 meters (12.1 to 42.7 feet). Their coloration is typically a mix of gray or black with white, and their bodies often bear scars from fights with other whales and from shark bites.2

A distinctive feature of most Mesoplodon species is that functional teeth are limited to one or two pairs in the lower jaw, usually erupting only in males. In some species, these teeth are tusk-like and curve upwards, partially holding the jaws shut. These whales are rapid swimmers and deep divers, making them seldom seen. Their diet primarily consists of squid, but they also consume fish and invertebrates.2
