Cuvier's beaked whale holds the records for both the deepest and the longest dives ever documented for any mammal; [24] in 2014, scientists reported that Cuvier's beaked whale, off the coast of California, dove to 9,816 ft (2,992 m) below the ocean's surface, becoming the deepest documented dive for any mammal.
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 ...
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.
When in their wintering waters, narwhals make some of the deepest dives recorded for cetaceans, diving to at least 800 m (2,620 ft) over 15 times per day, with many dives reaching 1,500 m (4,920 ft). [ 52 ] [ 53 ] The greatest dive depth recorded is 2,370 m (7,780 ft).
This whale's crusade dwarfed even the longest transits reported by the National Oceanic and Atmospheric Administration, which notes in a description of humpback whales shared on its site that some ...
A humpback whale has stunned scientists with a journey that spanned three oceans and more than 8,000 miles, setting the record for the longest known migration between breeding grounds.
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 humpback whale has been found travelling a record-breaking distance spanning three oceans to mate, raising an alarm about global challenges affecting the migratory behaviour of the species.
