Aquatic animals generally conduct gas exchange in water by extracting dissolved oxygen via specialised respiratory organs called gills, through the skin or across enteral mucosae, although some are evolved from terrestrial ancestors that re-adapted to aquatic environments (e.g. marine reptiles and marine mammals), in which case they actually ...

Marine biology studies species that live in marine habitats. Most of the Earth's surface is covered by ocean, which is the home to marine life. Oceans average nearly four kilometers in-depth and are fringed with coastlines that run for about 360,000 kilometres. [4] [5] Marine biology can be contrasted with biological oceanography.

Many animals feed on kelp and kelp provides sheltered habitats for yet others. Sea grass is the only type of flowering plant that grows in British seas, but it nonetheless forms vast beds. Invertebrates in coastal Britain are very diverse and include brittle stars , hermit crabs , mussels , prawns , sponges , sea anemones and sea squirts .
This list includes animals which either live entirely marine lives, or which spend critical parts of their lives at sea. The geographical range is south of Perth, Western Australia and the border of New South Wales and Queensland , including the whole of the coasts of South Australia and Tasmania and their offshore islands.
