Today, the consumption of marine mammals is much reduced. However, a 2011 study found that the number of humans eating them, from a surprisingly wide variety of species, is increasing. [ 1 ] According to the study's lead author, Martin Robards, "Some of the most commonly eaten animals are small cetaceans like the lesser dolphins...
Marine mammals comprise over 130 living and recently extinct species in three taxonomic orders. The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. [1] This list follows the Society's taxonomy regarding and subspecies.
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. They are an informal group, unified only by their reliance on marine ...
All marine mammals are protected under the Marine Mammals Protection Act of 1972. Bottlenose dolphin (Tursiops truncatus) Grey seal (Halichoerus gryphus) Can be distinguished from the harbor seal by its larger size, W-shaped nostrils, and preference to lay flopped out with its back flippers down when resting out of the water. Will rest on jetties.
Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish.Shellfish include various species of molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins).
They provide habitats and food for a diversity of marine life comparable to coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial ...
[56] [57] Antarctic krill is the keystone species of the Antarctic ecosystem beyond the coastal shelf, and is an important food source for marine mammals and birds. [ 66 ] The IPCC (2019) says marine organisms are being affected globally by ocean warming with direct impacts on human communities, fisheries, and food production. [ 67 ]
The California sea lion is used in military applications by the U.S. Navy Marine Mammal Program, including detecting naval mines and enemy divers. In the Persian Gulf , the animals can swim behind divers approaching a US naval ship and attach a clamp with a rope to the diver's leg.
