Whale feces, the excrement of whales, has a vital role in the ecology of oceans, [2] earning whales the title of "marine ecosystem engineers." This significant ecological role stems from the nutrients and compounds found in whale feces, which have far-reaching effects on marine life. Nitrogen and iron chelate released by cetacean species offer ...
A beluga whale is flensed in Buckland, Alaska in 2007, valued for its muktuk which is an important source of vitamin C in the diet of some Inuit. [ 1 ] Whale meat, broadly speaking, may include all cetaceans (whales, dolphins, porpoises) and all parts of the animal: muscle (meat), organs (offal), skin (muktuk), and fat (blubber).
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
Marine mammals are a food source in many countries around the world. Historically, they were hunted by coastal people, and in the case of aboriginal whaling, still are. This sort of subsistence hunting was on a small scale and produced only localised effects. Dolphin drive hunting continues in this vein, from the South Pacific to the North ...
Krill are crustaceans and, as do all crustaceans, they have a chitinous exoskeleton. They have anatomy similar to a standard decapod with their bodies made up of three parts: the cephalothorax is composed of the head and the thorax, which are fused, and the abdomen, which bears the ten swimming appendages, and the tail fan. This outer shell of ...
Cetacea (/ sɪˈteɪʃə /; from Latin cetus ' whale ', from Ancient Greek κῆτος (kêtos) ' huge fish, sea monster ') [ 3 ] is an infraorder of aquatic mammals belonging to the suborder Whippomorpha that includes whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size ...
Modern bowhead and right whales are species that use filter-feeding techniques to eat, sifting material through plates of baleen as they swim with their mouths open near the ocean’s surface to ...
However, Japanese do eat krill, [55] and krill is also used in large quantities by fish farms as feed. [56] Pauly's report also claims that the locations where whales and humans catch fish only overlap to a small degree, and he also considers more indirect effects of whales' diet on the availability of fish for fisheries.
