The common yabby, Cherax destructor, is an Australian freshwater crustacean. It is in the Parastacidae family. It is listed as a vulnerable species of crayfish by the World Conservation Union (IUCN).[1] But wild yabby populations remain strong, and have expanded into new habitats created by reservoirs and farm dams.[2]
Its common name of "yabby" is also applied to many other Australian Cherax species of crustacean. The name is also applied marine ghost shrimp of the infra-order Thalassinidea. Yabbies occasionally reach up to 30 cm (12 in) in length but are more commonly 10–20 cm (4–8 in) long.[3]
Colour is highly variable and depends on water clarity (how clear it is) and habitat. Yabbies can range from black, blue-black or dark brown in clear waters to light brown, green-brown or beige in dark waters.[4] Yabbies specifically bred to be a vibrant blue colour are now popular in the aquarium trade in Australia.
