A largely unknown species endemic to the Gulf of Papua (Papua New Guinea), a limited distribution subject to a high degree of habitat destruction (high pollutant loads and dynamite fishing practices). Gold mining in the Fly River catchment contributes a large pollutant load that drains directly into the Gulf of Papua causing habitat damage. Hemiscyllium hallstromi may also be dependent on coral reef habitats, which are being heavily impacted by pollution and destructive fishing. This species may be subject to exploitation by the aquarium industry, but the extent is unknown.
|Range Description:||H. hallstromi is known to occur in the Western South Pacific, exclusively in Papua New Guinea (Gulf of Papua).|
Native:Papua New Guinea
|FAO Marine Fishing Areas:||
Pacific – western central

|Population:||Little is known about the population size in this range and no scientific data are currently available.|
|Habitat and Ecology:||This species resides in coastal tropical waters possibly on coral reefs. H. hallstromi reaches a maximum size of 77 cm total length (TL). Males mature between 48 to 64 cm TL. The biology of this species is almost entirely unknown.|
|Major Threat(s):||It is unknown if this species is utilized by the aquarium industry. However, this is a very attractive and hardy species that may be sought after for public and private aquaria. This small population is very susceptible to habitat destruction via high pollutant levels and dynamite fishing practices.|
|Conservation Actions:||There are currently no conservation measures in place for this species. Based on the restricted distribution of this species and high risk of habitat destruction this species requires scientific examination to assess its conservation status.|
