Hemigrapsus sanguineus
Taxonomic Group: Crustaceans-Crabs


Hemigrapsus sanguineus, the Asian Shore Crab, is native to the rocky shores of the Western Pacific, from Sakhalin and Peter the Great Bay (Russia), Korea, Japan and China. It has been introduced to the East Coast of the US, Northern Europe,and the Mediterranean Sea. It is associated primarily with natural and artificial intertidal rocky habitats, but has also been collected in salt marshes and subtidal habitats. Ballast water is the most likely vector for its initial introduction, though ship fouling and natural dispersal of larvae have likely contributed to its local spread. By preying on, and competing with, other intertidal species, Hemigrapsus sanguineus has had major ecological impacts on intertidal communities on the East Coast.
