Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale , which is the largest known animal that has ever lived.
Northern bottlenose feed mainly on deep water squid, primarily Gonatus sp., and bottom fish, such as Greenland halibut. [16] Foraging dives can last an hour or more at depths reaching over 1000 meters. [17] A small percentage of northern bottlenose whales have also been observed feeding on redfish, rabbitfish, spiny dogfish, and skate. [10]
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
Right whales feed mainly on copepods and other small invertebrates such as krill, pteropods, and larval barnacles, generally by slowly skimming through patches of concentrated prey at or below the ocean surface. [2] Sei whales and basking sharks (sometimes minke whales as well) are in positions as food competitors and are known to feed in the ...
Blue whales appear to avoid directly competing with other baleen whales. [81] [82] [83] Different whale species select different feeding spaces and times as well as different prey species. [73] [84] [85] In the Southern Ocean, baleen whales appear to feed on Antarctic krill of different sizes, which may lessen competition between them. [86]
Almost all of the 400 North Atlantic right whales live in the western North Atlantic Ocean. In northern spring, summer and autumn, they feed in areas off the Canadian and northeast U.S. coasts in a range stretching from New York to Newfoundland. Particularly popular feeding areas are the Bay of Fundy and Cape Cod Bay.
It was seen in the Pacific Ocean off Colombia in 2017, then popped up several years later near Zanzibar in the Indian Ocean - a distance of at least 13,000 km. ... Humpback whales live in all ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
