Asian Shore Crab (Hemigrapsus sanguineus)

Asian Shore Crab(Hemigrapsus sanguineus) zoea

Collected: Assateague, VA, 500 m from shore using an epibenthic sled fitted with plankton net, 365 micrometer mesh.

Notes: The Asian shore crab is a recently introduced species first found in New Jersey in 1988. It has since spread rapidly, and the adult is now reported from to Maine to North Carolina. This is the first report of wild-caught larvae in the plankton. It was relatively common in these June collections off of Assateague.

Collected by: Bill Johnson, Goucher College.

Hemigrapsis (early zoea)
The longish, ventrally directed lateral spines off of the carapace, seen in some stages, show up well in this posterior view. The spines on the larva below show exhibit a  less marked ventral bend. Such variations are common in some species.
