Imposter trevally
The imposter trevally, ''Carangoides talamparoides'' (also known as the imposter jack or white-tongued trevally) is a species of small coastal marine fish in the jack family Carangidae. The imposter trevally is distributed through the tropical waters of Indian and west Pacific oceans, from the Gulf of Oman in the west to Japan and Australia in the east. The species is quite similar to the Malabar trevally, but can be distinguished by its gill raker count, and is identifiable from other species by having a white to pale grey tongue. It is a relatively small species, growing to a maximum recorded length of 30 cm. The imposter trevally inhabits coastal waters of the continental shelf in depths of up to 140 m, often associating with closely related carangid species. It preys on a range of small fish, crustaceans and cephalopods, but little is known of its reproductive biology. The imposter trevally is of minor importance to fisheries throughout its range, taken by hook and line, bottom trawls and several types of artisanal gear.
==Taxonomy and naming==
The imposter trevally is classified within the genus ''Carangoides'', one of a number of groups of fish referred to as jacks and trevallies. ''Carangoides'' is further classified in the family Carangidae, itself part of the suborder Percoidei and the order Perciformes; the perch-like fishes.
The species was first scientifically described by the Dutch ichthyologist Pieter Bleeker in 1852 based on the holotype specimen taken from western Sumatra in Indonesia. Bleeker named this new species ''Carangoides talamparoides'', with the specific epithet having a slightly ambiguous meaning. ''Talam'' is a length measurement spanning the length of the thumb to little finger, ''par'' is Greek for 'equal' and ''oides'' translates to 'like' - possibly indicating the small size of the holotype. Bleeker's classification is still considered to be correct to this day, with some authors incorrectly reassigning the species to ''Caranx'', and only one junior synonym has been applied; ''Carangoides gibber'' by Henry Weed Fowler.
