Common stingaree

<em>Trygonoptera testacea</em>, commonly known as the common stingaree, is a small elasmobranch fish in the family Urolophidae, endemic to the coastal and estuarine waters of southeastern Australia. This species typically inhabits shallow sandy and muddy soft-sediment habitats in bays, estuaries, and shallow coastal waters along the Australian coastline. Its geographic range is restricted to the temperate waters of southeastern Australia, including areas around Victoria, New South Wales, South Australia, and Tasmania. Classified as Near Threatened on the IUCN Red List, <em>Trygonoptera testacea</em> faces pressures from bycatch in inshore trawl fisheries and habitat degradation of the shallow coastal environments on which it depends. Like other stingarees, the species possesses one or more venomous tail spines used defensively against predators. It is carnivorous, typically feeding on benthic invertebrates including small crustaceans, polychaete worms, and molluscs foraged from soft sediment. The species typically gives birth to live young following viviparous reproduction, a characteristic of the family Urolophidae. Biological traits such as average lifespan in years, precise disc width measurements, and body weight remain poorly documented in the scientific literature for this species.
