Yellow shovelnose stingaree
The yellow shovelnose stingaree (''Trygonoptera galba'') is a little-known species of stingray in the family Urolophidae, endemic to the outer continental shelf off Western Australia at a depth of . Growing to long, this species has an oval pectoral fin disc with a rather elongated, triangular snout, and a short tail with a caudal fin but no dorsal fin. There are prominent lobes outside of its nostrils, and a skirt-shaped flap of skin with a deeply fringed trailing margin in between. Above, this ray is an almost completely uniform light to dark yellow color, which darkens on the caudal fin. The International Union for Conservation of Nature (IUCN) lacks sufficient information to assess the yellow shovelnose stingaree beyond Data Deficient, though there is minimal fishing within its range.
==Taxonomy==
The first specimens of the yellow shovelnose stingaree were collected by the Taiwanese ship FV ''Hai Kung'' during the winter of 1981, when it was conducting exploratory fishery surveys off Western Australia. The ray was provisionally identified as ''Trygonoptera'' "sp. A" before being formally described by Peter Last and Gordon Yearsley in a 2008 Commonwealth Scientific and Industrial Research Organisation (CSIRO) publication. The specific epithet is derived from the Latin ''galbus'' ("yellow"), in reference to its coloration. The type specimen is a long adult male caught off the Houtman Abrolhos.〔 This species is closely related to the western shovelnose stingaree (''T. mucosa'').〔
