Krill are small crustaceans primarily found in the ocean, with the most notable type being Antarctic krill (Euphausia superba), which is crucial to the Southern Ocean ecosystem. Other types include the Pacific krill (Euphausia pacifica) and Northern krill (Meganyctiphanes norvegica), found in the North Atlantic. Each species varies in habitat, size, and role in the food web, serving as a vital food source for many marine animals, including whales, seals, and fish. Krill are also significant for their role in nutrient cycling and carbon sequestration in marine environments.
