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.
Plunging to 2,250 metres (7,380 ft), it is the third deepest diving mammal, exceeded only by the southern elephant seal and Cuvier's beaked whale. [ 6 ] [ 7 ] The sperm whale uses echolocation and vocalization with source level as loud as 236 decibels (re 1 μPa m) underwater, [ 8 ] [ 9 ] the loudest of any animal. [ 10 ]
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.
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 ...
Monterey Bay Whale Watch said the dolphins were spotted by the company's scouting boat when it went out to "perform a survey on the coast south of Monterey." ... More about deep-diving Risso's ...
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]
The greatest dive depth reported from tagged blue whales was 315 meters (1,033 ft). [69] Their theoretical aerobic dive limit was estimated at 31.2 minutes, [70] however, the longest dive measured was 15.2 minutes. [69] The deepest confirmed dive from a pygmy blue whale was 506 meters (1,660 ft). [71]
A wildlife charity has said the number of whale sightings off the Cornish coast has "gone through the roof" in the last few years. Bex Allen from Cornwall Wildlife Trust, said monthly surveys show ...
