Invasive Species

Rhithropanopeus harrisii is a small estuarine crab native to the Atlantic Coast of North America. It has invaded many locations in Europe and North America and is presumed to have dispersed mainly via oyster translocations and shipping. Anecdotal reports indicate that it can alter food webs, compete with native species, foul pipe systems, and be a vector of the white spot baculovirus.
