Generally, the Blue Swimmer Crab occurs in the deeper waters of intertidal estuaries but occasionally it enters shallower waters.
The Blue Swimmer Crab is found from Northern Queensland to Eden in New South Wales; Western Australia and the South Australian gulfs; also New Zealand and New Caledonia.
The Blue Swimmer Crab is a popular food in Australia and is targeted and caught in large numbers by professional and recreational fishers. These crabs enter estuaries as juveniles and grow quite quickly, maturing after one year.
