 This species occupies the tropical Australian coastal waters from Western Australia through the Northern Territory to Queensland.

Mating and reproduction

 Found most often in summer in inshore waters as they feed on bay-dwelling prawns, coastal mangroves, creeks and rivers. They can swim toward movement and may go into the shallows on hot, cloudy, still days in search of prey which, in the summer wet season, can lead to stings in murky coastal river waters.
