The fringefin trevally, fringe-finned trevally, round-finned trevally, or reef herring, ''Pantolabus radiatus'', is a species of inshore marine fish classified in the jack and horse mackerel family Carangidae. A relatively small fish, the fringefin trevally is known to reach , but is mostly encountered at lengths less than . The fringefin trevally has an ovate body, with distinctive orange-yellow fins and a black opercular spot. The dental patterns of the species distinguish it from the closely related scads of the genus ''Alepes''. Males have characteristic elongated dorsal and anal fins which produce a series of trailing filaments. The fringefin trevally is restricted to the waters of the Indo-Pacific, ranging from northern Australia to Papua New Guinea and eastern Indonesia. An inshore species, it is found in coastal and estuarine environments and exhibits daily and seasonal movements. The fringefin trevally is predatory, taking crustaceans as prey. The species is often taken as bycatch in prawn trawls and occasionally taken by anglers. ==Taxonomy and naming== The fringefin trevally is the only member of the monotypic genus ''Pantolabus'', one of around 30 genera in the jack and horse mackerel family Carangidae, a group of perciform fishes in the suborder Percoidei. The fringefin trevally was scientifically described by the Australian naturalist William Macleay in 1881 based on the holotype specimen taken in Rockingham Bay of Queensland, Australia. He named the species ''Caranx radiatus'', with the specific epithet derived from the Latin word for 'radiating' in reference to the elongated fin filaments. Two years later in 1883, Macleay unknowingly redescribed the same species as ''Caranx compressus'', again from a Queensland-caught specimen. The American ichthyologist Samuel Garman also redescribed the species as ''Caranx parasitus'' in 1903. These later names are considered junior synonyms under ICZN rules and considered invalid. The current generic name arose after the Australian ichthyologist Gilbert Whitley examined Garman's ''Caranx parasitus'' and concluded it warranted placement in a separate genus with close affinity to the genus ''Alepes''. He named the genus ''Pantolabus''; in his description he gives no explanation of the etymology, but it likely is derived from a Latin name for men, most notably the character of the same name in Horace's ''Satires''. In 1937, Whitley also revised ''Caranx radiatus'', placing it a separate new genus; ''Absalom''. Further revisions recognised the priority of ''Caranx radiatus'' as the first description and agreed with the placement in a monotypic genus. Since Whitley's ''Pantolabus'' came first, it had priority, creating the currently accepted name of ''Pantolabus radiatus''. The species is commonly referred to as the fringefin or fringe-finned trevally in reference to the elongated dorsal and anal fin lobes. Other less commonly used names include round-finned trevally and reef herring. The fringefin trevally was included in a phylogenetic study based upon morphological characteristics by Soko Gushiken. This found the species to be most closely related to the scad genus ''Alepes'', included in a larger monophyletic grouping of scads and horse mackerels as part of the subfamily Caranginae. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fringefin trevally」の詳細全文を読む スポンサード リンク
