Seafood is any form of marine life regarded as food by humans. Seafoods include fish, molluscs (octopus and shellfish), crustaceans (shrimp and lobster), echinoderms (sea cucumber and sea urchins). Edible sea plants, such as some seaweeds and microalgae, are also seafood, and are widely eaten around the world, especially in Asia (see the category of sea vegetables). In North America although not generally in the United Kingdom, the term seafood applies also to any fresh water life eaten by humans, so all edible aquatic life can be referred to as seafood.
