Coastal stingaree

Coastal stingaree (Urolophus orarius) is a small batoid ray in the family Urolophidae, endemic to shallow coastal waters of southern Australia, particularly along the coasts of South Australia, Victoria, and Tasmania. Like other stingarees, it has a rounded disc, a short tail armed with one or two venomous spines, and lacks a distinct rostrum. It inhabits sandy and muddy nearshore substrates in depths typically less than 30 metres, where it forages for polychaete worms, crustaceans, and small molluscs buried in the seabed. Females are ovoviviparous, giving birth to small litters of live young following internal development. Coastal stingaree is assessed as Endangered by the IUCN, driven by its restricted range, slow reproductive rate, and significant bycatch in inshore commercial and recreational fisheries operating across southern Australian coastal waters. Bottom trawling, prawn trawling, and gillnetting are identified as major threats. The species receives limited targeted conservation attention and is not currently the subject of specific fisheries management measures. Its small home range and coastal distribution make it especially vulnerable to localised fishery impacts.
