CIESM Atlas consists of four volumes (fish, crustaceans, molluscs, and macrophytes), each written by a group of specialists in their respective field. Individual species pages are designed to stand alone as information sheets with illustrations, diagnostic features, biological information, references and a distribution map for each exotic species.
These distribution maps have been digitized by the EASIN team and have been included in the EASIN geodatabase. More specifically, we have included spatial data for 394 marine species: 83 fish, 66 crustaceans, 136 molluscs and 109 macrophytes.
