Deepest-Diving Marine Animals
The record dive depths of air-breathing marine animals, in metres. Cuvier's beaked whale holds the record at 2,992 m - nearly 3 kilometres down - the deepest dive ever documented for any mammal or air-breathing animal.
About This Dataset
Deepest-Diving Marine AnimalsCuvier's beaked whale (2,992 m) is the undisputed champion, diving roughly 600 m deeper than the southern elephant seal (2,388 m) and 740 m deeper than the mighty sperm whale (2,250 m), the classic deep-diver of whaling lore. All three descend to crushing depths where no light penetrates, holding their breath for well over an hour to hunt squid and fish. A clear gap separates these elite mammals from the leatherback turtle (1,280 m), the deepest-diving reptile, and the emperor penguin (534 m), the deepest-diving bird. The ranking shows that extreme diving is overwhelmingly a marine-mammal specialty, driven by adaptations - collapsible lungs, oxygen-rich muscle and slowed heart rates - that let them exploit a food supply hidden thousands of metres below the surface.
