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.
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).
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 ...
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 ...
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 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 male humpback has completed the longest recorded migration for a whale from South America to Africa. Scientists explain why this journey is so unusual. Male humpback whale makes record-breaking ...
