Color
Body bluish dorsally, golden-white ventrally; Anal and caudal fins yellowish; Row of about 12 dark blue blotches along base of second dorsal fin, four blotches triangular, the remainder rectangular; Six dusky longitudinal strips (as large as eye diameter); Dorsal fin bluish-gray; Dark blue spot on posterior end of opercle.
Etymology
Carangichthys: from French, caranx = carangue, the name of a Caribbean fish + from Greek, ichthys = fish. Related to both Caranx and Carangoides. Philibert Commerson (1727-1773) was a French explorer and naturalist, he says he derived the name caranx from the Greek word meaning head, and justifies this etymology, because these fishes, according to him, prevail by the head (quia capite prœvalent), and because the saurel (se. trachurus) exerts a kind of tyranny on the fishes of the coasts (principatum et tyrannidem exercet inter littorales pisces). These are singular reasons, and one has all the more reason to be surprised that a man such as Commerson had recourse to them, as he had certainly not been looking for his name so far. More than a century before him, the French colonists of the West Indies called the species of this kind that they caught on their coasts carangue: We can be sure of this by the testimony of Dutertre, Rochefort, Plumier and Labat; And as there is no appearance that the first and ignorant inhabitants of our islands had the idea of making up a Greek name for an American fish, there is every reason to believe that they simply corrupted into carangue the name of acarauna, used in Brazil and among the Spanish and Portuguese colonists for several chetodons and other very compressed fish. The name of carangue is nowadays general among our French sailors for fishes of the present kind that are caught in the torrid zone, and especially for those of a high shape; And Commerson himself tells us that no other name is used at Isle-de-France. It even seems, according to Duhamel, that this name was brought to Europe by sailors, and that in some places of our coasts it is given to the ordinary saurel; Finally, Barbot already has it, and disguises it as corango. Histoire naturelle des poissons par Mr Georges Cuvier et par Mr Valenciennes Tome neuvième, 1833.
dinema: from Greek prefix, dis = two times + from greek, nema = thread. Named in reference of the anteriormost rays of second dorsal and anal fins longest, greatly extended.
