Justification:
This small endemic catshark is recorded from a small area off the northwest coast of Australia with a depth range of 59 to 252 m. Its very small size means that it is unlikely to be significantly impacted by the trawl fisheries in the area. In addition it is probably discarded when caught due to its size and low commercial value, and is believed to have a high survival rate.
