The species is distributed along the coast of tropical Africa in the eastern Atlantic Ocean, extending to the Mediterranean Sea. Adults live predominantly in shallow waters shallower than 70 m deep, often forming small schools. The African threadfish is similar in appearance to the closely related and co-occurring African pompano, with the slightly concave shape of the species head profile the most definitive feature of the species. Like other members of the genus ''Alectis'', the juveniles of the species have long trailing dorsal and anal fins. The African threadfish is of minor commercial importance, and is also considered to be a game fish. ==Taxonomy and naming== The African threadfish is one of three members of the diamond trevally genus ''Alectis'', which is one of 33 genera in the jack and horse mackerel family Carangidae. The Carangidae are perciform fishes in the suborder Percoidei. The species has a complex taxonomic history, which is based on only two scientific descriptions. The first description was made by the French naturalist Étienne Geoffroy Saint-Hilaire in 1817, in which he named the species ''Gallus alexandrinus'', using the generic name ''Gallus'' which had been created by Lacépède after he recognised the genus distinct from ''Zeus'', a genus of dories. However, ''Gallus'' was preoccupied by a bird, leading to the reassignment of the species to at least six different genera, before the species was placed in ''Alectis''. The second description was made by Georges Cuvier in 1833 under the name of ''Gallichthys aegyptiacus''. This name was also re-evaluated twice, before the description was discarded as a junior synonym of ''A. alexandrina''. The species has also been incorrectly referred to as ''Alectis alexandrinus''. However the genus is feminine and so ''alexandrina'' is the correct spelling. The common names 'African threadfish' and 'Alexandria pompano' are in reference to the species prominent distribution around Africa, as well as the thread like appearance of the juveniles dorsal and anal fins. 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「African threadfish」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
