|Scientific Name:||Urolophus piperatus Séret & Last, 2003|
Urolophus sp. B ssp.
|Taxonomic Notes:||It is possible that there may be two species provisionally identified as U. piperatus based on differences between size at maturity, however no consistent intraspecific differences were found between them based on morphometric or meristic data (Séret and Last 2003).|
|Red List Category & Criteria:||Least Concern ver 3.1|

A small stingaree species endemic to the Coral Sea off Queensland, Australia. Occurs on the outer continental shelf and upper slope at depths of 171 to 370 m. Only recently described and virtually nothing known of its biology but likely to have low fecundity (1 to 2 young/year) as with other urolophids. Area of occurrence receives very little fishing pressure from the Coral Sea Fishery as there are only two operators in the trawl sector of this fishery. If fisheries expanded in the Coral Sea, U. piperatus could be potentially threatened given its narrow range. However, at present no reason to suspect that there is any threat to this species.
|Range Description:||Narrow ranging, northeastern Australian endemic: Northern Queensland from Mackay to Cairns, including the Saumarez and Marion Reefs (Last and Stevens 1994, Séret and Last 2003).|
Native:Australia (Coral Sea Is. Territory, Queensland)
|FAO Marine Fishing Areas:|
Pacific – western central

|Habitat and Ecology:||Occurs on the continental shelf edge and upper slope at 171 to 370 m depth (Séret and Last 2003). Nothing known of its biology. Likely to have low fecundity (1 to 2 young/year) as with other urolophid species (for example see White et al. 2001).

|Major Threat(s):||Area of occurrence receives very little fishing pressure from the Commonwealth managed Coral Sea Fishery (CSF). There are only two operators in the trawl sector of the CSF, which fish a maximum of 20 days per year, thereby exerting a very low effort (AFMA 2003). If fisheries expanded in the Coral Sea, U. piperatus could be potentially threatened given its narrow range.|
Monitoring of fishing effort in the region and research into the life history of the species.
The effective implementation of the Australian National Plan of Action for the Conservation and Management of Sharks (e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) should help facilitate the conservation and management of all elasmobranch species in Australia.
