Justification:
This possibly obligate freshwater species is recorded from several rivers in South East Asia and northern Australia and is probably unrecorded in others. The potential for exchange between these subpopulations is presumably very limited. The species has been and will continue to be adversely affected in much of its range by a complex of factors including directed and bycatch fisheries and habitat alteration or destruction. The possibility of extinction in the wild for some subpopulations is considered extremely high, but the status of those in Australia is probably favourable.
