Beaked whales have several anatomical adaptations to deep diving: large spleens, livers, and body shape. Most cetaceans have small spleens. However, beaked whales have much larger spleens than delphinids, and may have larger livers, as well. These anatomical traits, which are important for filtering blood, could be adaptations to deep diving.
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 ...
Perrin's beaked whale (Mesoplodon perrini) is part of the toothed whale suborder and is one of over 90 known cetaceans in existence today. [3] Beaked whales are part of the family Ziphiidae , which are the second most diverse group out of all marine mammals with over 20 species currently recognized. [ 4 ]
The five-meter-long creature, a type of beaked whale, was identified after it washed ashore on an Otago beach from its color patterns and the shape of its skull, beak and teeth.
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.
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 species was formally described in 1991, based on ten specimens obtained from Peru between 1976 and 1989, including a 3.72 m (12.2 ft) adult male as the type specimen. A specimen that stranded at Paracas, Peru in 1955 (first tentatively identified as Andrews' beaked whale) has since been identified as a pygmy beaked whale. Since 1987, there ...
Some whales, such as the sperm or Cuvier's beaked, can spend over an hour between breaths, the Whale and Dolphin Conservation reports. It may not look like it, but whales have hair .
