This species is very rare, only 9 have every been collected.  New Guinea river sharks are endangered for several reasons.  Since many of them are restricted to fresh water environments they are more susceptible to being caught in fisheries.  Also habitat degradation is a major concern for this species.  Since the population is already very small, possibly less then 250 species, their endangered status is very serious.
