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
The gray whale (Eschrichtius robustus), [1] also known as the grey whale, [5] is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters (49 ft), a weight of up to 41 tonnes (90,000 lb) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age.
Whales are typically hunted for their meat and blubber by aboriginal groups; they used baleen for baskets or roofing, and made tools and masks out of bones. [124] The Inuit hunt whales in the Arctic Ocean. [124] The Basques started whaling as early as the 11th century, sailing as far as Newfoundland in the 16th century in search of right whales.
The belly meat, in the striped bellows-like underbelly of baleen whales "from the lower jaw to the navel", [15] is called unesu (ウネス（畝須）) and is known for being made into whale bacon. [15] [24] The prized tail meat, called onomi (尾の身) or oniku (尾肉) are two
Pilot whale meat (bottom), blubber (middle) and dried fish (left) with potatoes, Faroe Islands. For thousands of years, indigenous peoples of the Arctic have depended on whale meat and seal meat. The meat is harvested from legal, non-commercial hunts that occur twice a year in the spring and autumn. The meat is stored and eaten throughout the ...
The whales eat amphipod crustaceans like tiny shrimp and worms, which they consume by sucking up water and sediment from the seafloor, where such creatures live, then using their baleens to filter ...
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.
