Ecological Risk Screening Summary - Brazos Dwarf Crayfish (Cambarellus texanus) - 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.

Cambarellus texanus is a freshwater crayfish native to Texas. It inhabits ditches with standing water and emergent vegetation, and will burrow when the habitat becomes dry. The species is present but very rare in the aquarium trade in Germany and the Czech Republic, and not reported to be traded in the U.S. No introductions of this species have been reported outside its native range. Climate match with the contiguous United States is high, with highest match in Texas and Georgia. Overall risk posed by this species is uncertain.
