To understand the hunting and foraging behavior of beaked whales, researchers used sound and orientation recording devices on two species: Cuvier's beaked whale (Ziphius cavirostris) and Blainville's beaked whale (Mesoplodon densirostris). These whales hunt by echolocation in deep water (where the majority of their prey is located) between ...
The pygmy beaked whale (Mesoplodon peruvianus), also known as the bandolero beaked whale, Peruvian beaked whale and lesser beaked whale, is the smallest of the mesoplodonts and one of the newest discoveries. There were at least two dozen sightings of an unknown beaked whale named Mesoplodon sp.
A pod of Baird's beaked whales surfacing. The species reaches lengths of about 11.9 metres (39 ft) for males and 12.8 metres (42 ft) for females. [6] The snout, called a beak, is elongated and lacks all teeth except for one or two sets in the lower mandible, which are called "battle teeth" for their use in intra-species conflict.
Cuvier's beaked whale, goose-beaked whale, or ziphius (Ziphius cavirostris) is the most widely distributed of all beaked whales in the family Ziphiidae. [7] It is smaller than most baleen whales —and indeed the larger toothed cetaceans (like orca and sperm whales )—yet it is large among the beaked whales and smaller cetaceans, appearing ...

Perrin's beaked whales have not definitively been recorded alive by scientists; however, its appearance is known from beached specimens. Perrin's beaked whales cannot be identified with absolute certainty at sea. However, the combination of small size, appearance, and a small presumed geographical range makes uncertainty unlikely.
The five-meter-long creature, a type of beaked whale, was identified after it washed ashore on an Otago beach from its color patterns and the shape of its skull, beak and teeth.
The four-toothed whales or giant beaked whales are beaked whales in the genus Berardius. They include Arnoux's beaked whale ( Berardius arnuxii ) in cold Southern Hemispheric waters, and Baird's beaked whale ( Berardius bairdii ) in the cold temperate waters of the North Pacific.
