Bumpnose trevally
The bumpnose trevally, ''Carangoides hedlandensis'' (also known as the bumpnose kingfish and onion kingfish) is a species of relatively small inshore marine fish classified in the jack family Carangidae. The bumpnose trevally is fairly common in the tropical and subtropical waters of the Indo-west Pacific region, ranging from South Africa in the west to Japan and Samoa in the east. It is a small species by carangid standards, reaching a maximum known length of 32 cm, and can be distinguished from the similarly shaped ''Carangoides armatus'' by a distinct 'bump' on the snout, which gives the fish its common name. The species inhabits coastal waters, often living along bays and beaches, where it takes shrimp, small crabs, and juvenile fish as prey. The bumpnose trevally is of minor importance to fisheries throughout its range, taken by hook and line, trawls, and seine nets. It is also of minor importance to anglers, taken by baits from beaches and piers, and is considered a modest table fish.
==Taxonomy and naming==
The bumpnose trevally is classified within the genus ''Carangoides'', a group of fish commonly called jacks and trevallies. ''Carangoides'' falls into the jack and horse mackerel family Carangidae, of the order Perciformes, in the suborder Percoidei.
The species, as it is currently accepted, was first described and classified by the Australian ichthyologist Gilbert Percy Whitley in 1934 based upon a sample taken from Port Hedland in Western Australia, which was designated to be the holotype.〔 〕 Whitley named the species ''Olistus hedlandensis'', placing the fish in what was at the time a valid genus of jacks. When ''Olistus'' was synonymised with ''Carangoides'', the fish was placed either in ''Caranx'' or ''Carangoides'', and is currently accepted as belonging in the latter. The specific epithet refers to the type location of the species, Port Hedland.〔 This was not the first time the fish had been described though, with Georges Cuvier applying the name ''Olistus malabaricus'' to the species in 1833, which would give it priority over Whitley's name. However, when ''Olistus'' was merged into ''Carangoides'', a taxonomic homonym was created with ''Carangoides malabaricus'', thus Whitley's name has been accepted to overcome this problem. The bumpnose trevally is very similar to ''Carangoides armatus'', and appears to have been misidentified as such many times, with 1980 review of the two species finding many misidentified fish in museum collections.〔
