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 ...
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 ...
Sowerby's Mesoplodon (Mesoplodon bidens) is a beaked whale that is smaller (4–6 m) [47] than Cuvier's Whale, with a longer, tapered beak. [49] Unlike the Cuvier Whale, this species does not appear to be spotted, [50] and the male's teeth are clearly visible but do not form prominences. [51]
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 current models of breath-hold diving do not adequately explain the natural diving behaviour of these whales. [12] In beaked whales, the descent rate was consistently faster than ascent rate, at about 1.5 metres per second, regardless of dive depth, and at a steep angle of from 60 to 85 degrees, Fluke rate for Z cavirostris was higher at the ...
Cuvier's beaked whale in Dominica. Cuvier's beaked whale, or goose-beaked whale, is the most common and abundant species of beaked whale. [124] It is sighted in all the oceans, from the tropics to the polar regions, excluding shallow waters and very high latitudes. [124]

The overwhelming majority of the cetaceans involved in sonar-associated beachings are Cuvier's beaked whales (Ziphius cavirostrus). Individuals of this species strand frequently, but mass strandings are rare. Cuvier's beaked whales are an open-ocean species that rarely approach the shore, making them difficult to study in the wild. Prior to the ...
