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 ...
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 ...
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.

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.
Beaked whales are among the longest and deepest divers of any cetaceans. Mean diving depth for Blainville’s beaked whale is 922m with maximum 1408 m. The species dives primarily to forage for food in the deep ocean, usually diving >800 m when foraging and can stay underwater for 48-68 min. For longer dives ascent rates are slower than descent ...
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 ...
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 ...
