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.
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 ...

[1] This list follows the Society's taxonomy regarding and subspecies.

A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web.
Marine mammals also feed on Raitt's sand eels but less regularly. Mostly species such as grey seals, harbour seals and harbour porpoise consume many sand eels in the spring and early summer. [22] Raitt's sand eels feed mainly on zooplankton. [23] By consuming zooplankton they act as a link through to the higher trophic level predators that eat ...
