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.
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.
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 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 ...
The greatest dive depth reported from tagged blue whales was 315 meters (1,033 ft). [72] Their theoretical aerobic dive limit was estimated at 31.2 minutes, [73] however, the longest dive measured was 15.2 minutes. [72] The deepest confirmed dive from a pygmy blue whale was 506 meters (1,660 ft). [74]
Nothing is currently known about the whales’ habitat. The creatures deep-dive for food and likely surface so rarely that it has been impossible to narrow their location further than the southern ...
The northern bottlenose whale is endemic to the North Atlantic Ocean and populations are found in the deep (>500 m) cold subarctic waters of the Davis Strait, the Labrador Sea, the Greenland Sea and the Barents Sea, but can range as far south as Newfoundland and Nova Scotia. As of 2017, the population in the North East Atlantic is estimated to ...
The whale would have had to cross multiple oceans and travel more than 8,000 miles from the Colombian Pacific to get there, and experts believe it was trying to find a mate or food.
