Comments: Record is based on WAM specimen from Cooper Creek, Qld. (Ref. 7300). Found from the east coast of lower Cape York Peninsula (Qld) between the Daintree river and Cape Tribulation (Ref. 44894). Juveniles and adults inhabit fresh and mildly brackish habitats (salinity<5) in streams of the Australian Wet Tropics (81% of the 36 records were from freshwater streams and collectively demonstrate that this species inhabits fresh water throughout all seasons). The species was not sampled or observed in the nearshore marine environment (Ref. 87298).
