Classification
Kingdom: Animalia
Phylum: Arthropoda
Class: Malacostraca
Order: Decapoda
Family: Portunidae
Genus: Carcinus
Leach, 1814
Species: Carcinus aestuarii
Carcinus maenas is found on all types of shore, from high water to depths of 60 m in the sublittoral, but it is predominantly a shore and shallow water species. It tolerates a wide range of salinities and is especially abundant in estuaries and salt marshes.
Identifying features:-
• Shell (carapace) up to 8 cm wide.
• Front of carapace serrated with five teeth either side of the eyes.
• Three rounded lobes between the eyes. Variable in colour from dark green to orange or red.
Females can distinguished from males by examining the vestigal abdomen on the underside of the crab. Males have a triangular abdomen, while in females, the abdomen is rounded and of equal breadth for most of its length.
Biology information:-
Carcinus maenas is an easily identifiable crab of estuaries, sheltered rocky shores and offshore waters (Crothers, 1968). With increasing exposure on rocky shores, Carcinus maenas is replaced by other crab species such as the velvet swimming crab Necora puber, the bristly crab Pilumnus hirtellus, the edible crab Cancer pagurus and Montagu's crab Xantho incisus, and on increasingly exposed sandy areas by Pennant's swimming crab Portumnus latipes, the masked crab Corystes
cassivelaunus, the harbour crab Liocarcinus depurator and the flying crab, Liocarcinus holsatus (Crothers, 1968).
