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 ...

Marino et al. 2000 estimated the adult body mass for Zygorhiza to 3,351 kg (7,388 lb) based on an estimated body length of 5.2 metres (17 ft). Using CT scans, they estimated the brain weight to 738.2 g (26.04 oz), resulting in an EQ value of 0.26 (compared to 0.54 for a modern cetacean such as Cuvier's beaked whale.) [13]
The sperm whale or cachalot (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
