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 ...
Not much information is available about group composition of beaked whales. Only four species have been studied in great detail: northern bottlenose whale, Blainville's beaked whale, Baird's beaked whale, and Cuvier's beaked whale. Female northern bottlenose whales appear to form a loose network of social partners with no obvious long-term ...
Cuvier's beaked whale (Ziphius cavirostris). The Cuvier's beaked whale , or Ziphius (Ziphius cavirostris), is a large species of beaked whale, measuring up to seven meters long and weighing seven tons, with a pointed, rather short beak (especially compared to mesoplodons), from which two prominent teeth protrude in males.

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 ...
A researcher fires a biopsy dart at an orca.The dart will remove a small piece of the whale's skin and bounce harmlessly off the animal. Cetology (from Greek κῆτος, kētos, "whale"; and -λογία, -logia) or whalelore (also known as whaleology) is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific ...
There are approximately 89 living species split into two parvorders: Odontoceti or toothed whales (containing porpoises, dolphins, other predatory whales like the beluga and the sperm whale, and the poorly understood beaked whales) and the filter feeding Mysticeti or baleen whales (which includes species like the blue whale, the humpback whale ...
Adult strap-toothed beaked whales show a distinctive colouration that perhaps makes them one of the most readily distinguishable beaked whale species. Adults have a white beak, with a pale white 'cape' that extends to halfway between the dorsal fin and head. The dorsal fin is set far back down the body and is white-tipped.
