Longnose trevally
The longnose trevally, ''Carangoides chrysophrys'' (also known as the tea-leaf trevally, club-nosed trevally, grunting trevally, and dusky trevally), is a species of inshore marine fish in the jack family, Carangidae. The species is distributed throughout the tropical and subtropical waters of the Indian and west Pacific Oceans from South Africa to New Zealand and Japan, inhabiting coastal waters, especially reefs, to a depth of 90 m. The longnose trevally is distinguished from similar species by a combination of a scaleless breast and the number of gill rakers and fin rays. It is a moderately large fish, growing to a maximum known length of 72 cm and 4.35 kg. The longnose trevally is a predatory fish, consuming small fish, crustaceans and molluscs. The species is of minor commercial importance throughout its range, and is considered to be a good table fish.
==Taxonomy and naming==
The longnose 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, itself part the order Perciformes, in the suborder Percoidei.
The species was first scientifically described by the French taxonomist Georges Cuvier in 1833, based on the holotype specimen collected from the waters of the Seychelles. He named the new species ''Caranx chrysophrys'', with the specific name meaning 'golden eyebrow' in Greek. The generic position of the species was revised twice, being placed in ''Citula'' by William Ogilby and finally into ''Carangoides'' by Ian Munro, where it has remained. The species has been independently described on a number of occasions, the first when Pieter Bleeker identified a fish he believed was similar, but not the same as ''Carangoides chrysophrys'', and named it ''Carangoides chrysophryoides''. Other synonyms include ''Caranx nigrescens'', ''Caranx jayakari'' and ''Caranx typus''. These are all considered to be junior synonyms under the ICZN rules and are no longer used. The species has a number of common names, with the most often used names, 'longnose trevally' (or 'longnose kingfish') and 'club-nosed trevally' in reference to the snout profile of the fish. The names 'dusky trevally' and 'grunting trevally' are used for the fish in the United States.
