Homarus gammarus

Homarus gammarus is the European lobster, a large clawed lobster native to the northeastern Atlantic and parts of the Mediterranean Sea. It is distinguished from the American lobster by its range and genetic lineage.

Homarus: Homarus is a genus of large clawed lobsters containing the European and American lobsters. This genus contains Homarus gammarus and its closest living relative.
Lobster: Lobsters are marine decapod crustaceans, including clawed, spiny, and slipper forms. Homarus gammarus is one species within the broader group commonly called lobsters.
Homarus americanus: Homarus americanus is the American lobster, a large clawed lobster native to the northwestern Atlantic Ocean. It is the European lobster’s closest living relative and occupies the opposite side of the Atlantic.
Lobster fishery: A lobster fishery is the harvesting of lobsters for food and commerce. Wild Homarus gammarus is caught in fisheries across its native range.
Decapoda: Decapoda is an order of crustaceans with five pairs of thoracic walking legs. Homarus gammarus belongs to this order of crabs, shrimps, and lobsters.
Benthic zone: The benthic zone is the ecological region at the bottom of a body of water. This lobster lives on the seabed, often sheltering among rocks and in crevices.
Spiny lobster: Spiny lobsters are marine decapods with long antennae and no enlarged crushing claws. They are often called lobsters but lack the large paired claws of Homarus gammarus.
Lobster pot: A lobster pot is a baited trap designed to capture lobsters and other crustaceans. Pots are a principal gear used to catch this species.
Chela (organ): A chela is a pincer formed by the movable and fixed parts of an arthropod appendage. Its enlarged first pair of legs bears the lobster’s characteristic claws.
Scavenging: Scavenging is feeding on dead or decaying organisms rather than killing them directly. Carrion forms part of the varied diet of this opportunistic lobster.
