Whales evolved from land-living mammals, and must regularly surface to breathe air, although they can remain underwater for long periods of time. Some species, such as the sperm whale, can stay underwater for up to 90 minutes. [2] They have blowholes (modified nostrils) located on top of their heads, through which air is taken in and expelled.
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 bowhead whale is not a social animal, typically travelling alone or in small pods of up to six. It is able to dive and remain submerged under water for up to an hour. The time spent under water in a single dive is usually limited to 9–18 minutes. [19] The bowhead is not thought to be a deep diver, but can reach a depth down to 150 m (500 ft).
The two were recorded showing off their incredible dance moves in a new video online. Get these two a TikTok account because we want to learn their routine! The whale and their trainer really have ...
And sperm whales function as a family, "Sperm whales are often spotted in groups (called pods) of some 15 to 20 animals. Pods include females and their young, while males may roam solo or move ...
Whales have an elongated head, especially baleen whales, due to the wide overhanging jaw. Bowhead whale plates can be 9 metres (30 ft) long. Their nostril(s) make up the blowhole, with one in toothed whales and two in baleen whales. [25]
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 ...
For example, when sperm whales are approached by boats they surface less, shorten the intervals between breathes and do not show their fluke before diving as often. [49] Cetaceans may also reduce their acrobatic surfacing behaviours, such as when humpback whale groups without calves are approached by vessels to within 300 m. [ 51 ]
