Palaemon elegans
Taxonomic Group: Crustaceans-Shrimp


Palaemon elegans, also known as the Rockpool Shrimp or the Rockpool Prawn, inhabits coastal rockpools, shallow rocky areas and man-made structures. It has a wide native range in the Northeast Atlantic, from the west coast of Norway to Namibia, and offshore islands, including the Azores, Cape Verde and Canary Islands. It has been introduced to the Baltic, Caspian, and Aral Seas, the Persian Gulf and Massachusetts. In parts of its introduced range, P. elegans has positive economic impacts through its use as food for commercial fish. It can also have negative ecological impacts by displacing native shrimp species.
