The common name, yabby, is an ambiguous term since it is also used to describe other Australian Cherax species (other than the smooth marron, Cherax cainii, and the hairy marron, Cherax tenuimanus) and Engaeus spp., and is also applied to some marine Decapoda (e.g. mud shrimp, infraorder Thalassinidea, such as the bass yabby, Trypaea australiensis Dana, 1852, a common species in southeastern Australia that is used as bait). The term yabby seems to derive from the word yabij in the aboriginal language, which was used by wandering tribes to describe the native crayfish from central Australia. The generic name Cherax is thought to be a misspelling of the Greek word 'charax', meaning a pointed stake
