Ecological Risk Screening Summary - Gaetice depressus (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.

Gaetice depressus, is an intertidal crab native to East Asia including China, including Hong Kong, Japan, South Korea, and Taiwan. The history of invasiveness is No Known Nonnative Population. Gaetice depressus has not been reported as introduced or established anywhere outside of its native range, therefore no impacts of introduction have been documented. This species is found in the aquarium trade in the United States. The overall climate match for the contiguous United States is High. The majority of the eastern contiguous United States had a medium match with areas of high matches found in Southeast and the eastern Midwest. The climate match does not account for salinity tolerance. Species establishment will require both a suitable climate and the availability of aquatic habitat with appropriate salinity. The certainty of assessment is Low due to a lack of information and salinity requirements. The overall risk assessment category for Gaetice depressus is Uncertain.
