Justification:
This little-known species is possibly an Australian endemic (it may also occur in Indonesia). It is not targeted by fisheries and is distributed over a reasonably large coastal range. These small sharks are unlikely to be significantly impacted as a bycatch species and at least a portion of the species' range is protected from fishing. This species may be utilized by the aquarium industry, but the extent of exploitation is unknown.
