In these offshore waters, Cuvier's beaked whales execute some of the deepest and longest recorded dives among whales, and extant mammals. The current published records are 2,992 m (9,816 ft) for dive depth and 222 minutes for dive duration as recorded by biologging instruments attached to individual whales.
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).
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 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.
The deep diving whales can dive to depths of 800–1,200 metres (2,600–3,900 ft), and when feeding, they generally prefer deep waters near the continental shelf or around seamounts, where high biological activity is present in shallower waters. [55] The deepest recorded dive is 1,777 metres (5,830 ft). [56] [57]
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 ...
