Longfin trevally
The longfin trevally, ''Carangoides armatus'' (also known as the longfin kingfish, longfin cavalla and armed trevally), is a species of inshore marine fish in the jack family, Carangidae. The species is common in tropical to subtropical waters of the Indo-Pacific, ranging from South Africa in the west to Japan in the east, typically inhabiting inshore reefs and bays. The species is easily distinguished by its elongate dorsal and anal fin lobes and filamentous dorsal rays, as well as its scaleless breast. Longfin trevally are pelagic predators, taking a variety of small fish, cephalopods and crustaceans, and reach sexual maturity at around 21 cm. The species has a maximum known length of 57 cm and weight of 3.5 kg. The longfin trevally has a very complex taxonomic history which is closely intertwined with another currently valid species, ''Carangoides ciliarius'', which may yet prove to be synonymous. Longfin trevally are of minor importance to fisheries throughout their range and are considered good table fish, and are occasionally taken by anglers.
==Taxonomy and naming==
The longfin 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 German naturalist Eduard Rüppell in 1830, based on a specimen taken from the Red Sea, which was designated to be the holotype. Rüppell named the species ''Citula armata'', placing his new species in what was at the time a valid jack genus created by Georges Cuvier in 1816. ''Citula'' was later synonymised with ''Pseudocaranx'', and all its members were re-examined and placed in a number of different jack genera. ''C. armata'' became ''Caranx armatus'', also masculinising the species name. Finally, the species was placed in ''Carangoides'' after re-examinations of its anatomy by a number of authors as part of a larger investigation into the taxonomy of the carangid fishes. The species was subsequently described independently under three different names, with Cuvier applying ''Caranx ciliaris'' to the species, Masamitsu Ōshima applying ''Citula pescadorensis'' and Yojiro Wakiya ''Caranx schlegeli''. These are all considered to be invalid junior synonyms under ICZN rules.
The complexities of this naming process has led to extensive confusion between this species, originally described as ''Citula armata'', and a very closely related species, ''Sciaena armata'', now probably a synonym of ''Carangoides ciliarius''. ''Sciaena armata'', originally named by Peter Forsskål in 1775, has never been definitively identified, but in the same volume he described ''C. armatus'' in, Rüppell created ''Citula ciliaria''. He was unsure if this species was the same fish Forsskål described as ''S. armatus'', and subsequent reviews of this species complex tend to keep Rüppell as the author. ''Carangoides armatus'' and ''Carangoides ciliarius'' were considered synonymous in a 1975 review of the species,〔 however some authorities still consider them both to be valid species.
