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 shufeldtii is a freshwater crayfish native to the Gulf Coastal Plain of the United States. In addition to its use in experimental biology, the species is prominent among crayfishes in the North American aquarium trade and is also present in the European aquarium trade. Climate match with the contiguous United States is high, with highest match in the Gulf Coastal Plain. No impacts of C. shufeldtii introductions to new locations in Louisiana and Georgia have been identified, but there is some evidence of competitive dominance over other dwarf crayfishes where their ranges overlap. More research is needed to understand the impacts from introductions for this species. Overall risk posed by this species is uncertain.
