Short, J. W., 2000. Freshwater Crayfish. Queensland Museum Information Sheet.

Over 100 species of freshwater crayfish (Arthropoda: Crustacea: Decapoda: Pleocyemata: Astacidea; Parastacidae) are known from Australia. More than 20 of these are native to Queensland, including the smallest species in the world, the Swamp Crayfish (Tenuibranchiurus glypticus), which reaches little over 25 mm in length. Several Australian crayfish grow to a very large size. The giant Tasmanian crayfish, Astacopsis gouldi, reaches approximately 4.5 kg in weight and is the world's largest freshwater crayfish.
