Ecological Risk Screening Summary - Caridina longidigita (freshwater atyid shrimp; 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.

Caridina longidigita is a freshwater shrimp native to Lake Poso in Sulawesi, Indonesia. Although it is in the aquarium trade in the U.S., this species has not been documented as established anywhere outside its native range. Very little is known about the biology or ecology of the species. C. longidigita has a low climate match with the contiguous U.S., with an area of slightly higher match in Florida. Certainty of this assessment is low; further information is needed to adequately assess the risk this species poses. Overall risk assessment category is uncertain.
