Ecological Risk Screening Summary - Neoeriocheir leptognathus (a crab, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

Neoeriocheir leptognathus is a crab native to the coastal waters of eastern China and southern Japan. It was previously in the genus Eriocheir, and there is still some controversy about the reclassification. N. leptoganthus is a coastal, brackish water species that can survive freshwater. This species has not been reported outside of its native range, so history of invasiveness is classified as No Known Nonnative Population. The overall climate match for the contiguous United States was Medium with an area of high match in northern Florida and coastal Georgia. Because no information was available indicating that N. leptognathus is capable of reproduction in freshwater, the climate match only refers to where the species might be able to survive and not necessarily where it may be able to reproduce. The certainty of assessment was Low due to the limited information regarding this species. The overall risk for this species is Uncertain.
