The Asian shore crab, Hemigrapsus sanguineus , is an invasive species that has rapidly spread across the Eastern United States coastline. First observed in North America in 1988, its range currently extends from Maine to North Carolina. H. sanguineus has adapted very well to this region and has displaced several native species as the dominant crab in rocky intertidal habitats. Although the Asian shore crab’s biology and interactions with native species has been well studied, larger scale impacts (economic, potential further spread, community ecology, etc.) are under researched. We collected specimen samples of H. sanguineus throughout its entire East coast range, analyzed morphological differences across latitudes to demonstrate trends, and identified contributing factors to highlight areas in need of further research.
