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 ...
Baird's and Arnoux's beaked whales are so similar that researchers have debated whether or not they are simply two populations of the same species. However, genetic evidence and their wide geographical separation has led them to be classified as separate. Baird's beaked whale is the second largest living species of toothed whale after the sperm ...

Size of Baird's beaked whale compared to an average human Size of Arnoux's beaked whale compared to an average human Size of Sato's beaked whale compared to a human The two established species, Baird's and Arnoux's beaked whales, have very similar features and would be indistinguishable at sea if they did not exist in disjoint locations.

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 ...

A San Diego-based ecotour operator has captured stunning aerial footage, perhaps first of its kind, showing Cuvier’s beaked whales swimming along the surface. Rare footage shows elusive ...
The body of the pygmy beaked whale is the rather typical spindle shape of the genus, although the tail is unusually thick. The melon is somewhat bulbous and slopes down into a rather short beak. The mouthline in males has a very distinct arch with two teeth protruding slightly from the gum line before the apex.
