Issue
The species Pseudocaranx cheilio (Snyder, 1904) is considered as valid in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697) following Randall (2007: Ref. 86689). The species Pseudocaranx georgianus (Cuvier, 1833) is considered as valid in CofF ver. May. 2011 following Smith-Vaniz & Jelks (2006: Ref. 76781), with Caranx luna Geoffroy Saint-Hilaire, 1817, Caranx platessa Cuvier, 1833, Caranx nobilis Macleay,1881, and Usacaranx archeyi Griffin, 1932 as synonyms. Caranx georgianus (now under Pseudocaranx is also a valid species.

Dorsale stekels (totaal) : 9; Dorsale zachte stralen (totaal) : 25 - 26; Anale stekels: 3; Anale zachte stralen: 21 - 22; Wervels: 25. Greenish blue above, silvery white below; midside of body with yellow stripe; opercle with black spot (Ref. 3197). LL with 20-26 scutes (Ref. 6390). With maxilla the rear edge sloping slightly forward to its main axis, a large, diffuse dark blotch on the operculum, and a lateral line with 57-78 scales in the curved portion and 34-46 posterior scutes (Ref. 33616).

Adults occur in bays and coastal waters, including estuaries (Ref. 9563). Juveniles usually inhabit estuaries, bays and shallow continental shelf waters, while adults form schools near the sea bed on the continental shelf (Ref. 6390). Schools are found at the surface, in mid-water and on the bottom and are often associated with reefs and rough bottom (Ref. 9072). Schools are sometimes mixed with Caranx koheru and Arripis trutta (Ref. 9072). Feed on plankton by ram-filtering and suction feeding and on bottom invertebrates (Ref. 9072, 30206). Eggs are pelagic (Ref. 4233). Cultured only in Japan. (Ref. 4931). One of the best table fish 'being indeed the salmon of St. Helena' (Ref. 5288).

They are usually partial spawners, releasing eggs in small batches at intervals over a period of several weeks (Ref. 27733).
