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 spongicola is a freshwater shrimp found only in Lake Towuti in Sulawesi, Indonesia. This species has no documented history of introduction outside its native range, although it is present in low numbers in the aquarium trade. C. spongicola has a low climate match with the contiguous United States. Certainty of this assessment is low; further information is needed to adequately assess the risk this species poses. Overall risk assessment category is uncertain.
