Atya scabra

Atya scabra is a species of freshwater shrimp in the family Atyidae. Atya scabra can reach a length of about 89 millimetres (3.5 in) in males, while females are generally smaller, reaching about 64 mm (2.5 in).[3] It lives on rocky bottoms in rivers connected to the Atlantic Ocean. The species is widespread from Mexico to Brazil, Jamaica, Hispaniola, and Puerto Rico. In Africa, it occurs from Liberia to Angola, the Cape Verde Islands and the islands of the Gulf of Guinea.[1]
