striped stingaree
The striped stingaree (''Trygonoptera ovalis'') is a common but little-known species of stingray in the family Urolophidae, endemic to shallow, inshore waters off southwestern Australia. Reaching long, this species is characterized by an oval, grayish to brownish disc with darker mask-like markings around the eyes and paired blotches at the center of the disc that are extended posteriorly into horizontal lines. Its nostrils have enlarged lobes on the outer margins and a skirt-shaped curtain of skin with a deeply fringed trailing margin in between. Its tail terminates in a relatively large leaf-shaped caudal fin, and bears a small dorsal fin just before the stinging spine. The rounded, flexible disc of the striped stingaree enable it to maneuver through the rocks, reefs, and seagrass that comprise its favored habitats. The International Union for Conservation of Nature (IUCN) has listed this species under Least Concern; it is seldom caught by fisheries due to its habitat preferences.
==Taxonomy==
The striped stingaree was described by Peter Last and Martin Gomon in a 1987 issue of ''Memoirs of the National Museum of Victoria''; its specific epithet ''ovalis'' means "oval" in Latin and refers to its shape. The type specimen, a female across, was trawled from the Great Australian Bight, south of Red Rocks Point, by the FRV ''Courageous'' on 3 March 1978. Other common names for this species include bight stingaree and oval stingaree.〔
