western trumpeter whiting
The western trumpeter whiting, ''Sillago burrus'', is a species of marine fish of the smelt whiting family Sillaginidae that is commonly found along the northern coast of Australia and in southern Indonesia and New Guinea. As its name suggests, it is closely related to and resembles the trumpeter whiting which inhabits the east coast of Australia and is distinguishable by swim bladder morphology alone. The species inhabits a variety of sandy, silty and muddy substrates in depths from 0 to 15 m deep, with older fish inhabiting deeper waters. Western trumpeter whiting are benthic carnivores which take predominantly crustaceans and polychaetes as prey. The species reaches sexual maturity at the end of its first year of age, spawning in batches between December and February The species is taken as bycatch with other species of whiting and shrimps in Australia.
==Taxonomy and naming==
The western trumpeter whiting is one of 29 species in the genus ''Sillago'', which is one of three divisions of the smelt whiting family Sillaginidae. The smelt-whitings are Perciformes in the suborder Percoidea.
The species was first recorded by Lt. Emery of the HMS Beagle during the Australian leg of its voyage, with the lieutenant making a detailed sketch of the fish. This sketch and description was received by John Richardson in 1842, from which he described and named the species ''Sillago burrus'' without designating a holotype specimen, and furthermore the original sketch has apparently been lost. The location where the specimen was taken is also uncertain, with McKay narrowing down the range to between Depuch and Barrow Islands in northern Western Australia, with New Guinea an outside possibility. In 1985 McKay designated a neotype from the Dampier Archipelago, Western Australia.
The species has only ever been assigned one synonym, ''S. maculata burrus'' by Whitley in 1948 with apparently no reason given for the reassignment, although McKay also treated the species as a subspecies of ''S. maculata'' in his comprehensive revision of the Sillaginidae.
