Eastern Atlantic: Along the west African coast from Sierra Leone to Angola (Ref. 57392). Reported from the Sine-Saloum Estuary in Senegal, the Gambia River in Gambia, the Fatala River in Guinea (Ref. 28587) and from Mauritania (Ref. 55783), but this is unconfirmed in Ref. 57392 and needs confirmation.

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 8; членистые (мягкие) лучи спинного плавника (общее число) : 24 - 28; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 21 - 24. Diagnosis: body elongate (depth comprised 2.4-3.1 times in fork length) and strongly compressed; eyes small; snout short and rounded; mouth small; end of upper jaw extending to below anterior eye margin; teeth present in jaws, absent on vomer; 1st dorsal fin with 7 spines, 2nd dorsal with 1 spine and 24-28 soft rays; anal fin with 2 detached spines, followed by 1 spine and 21-24 soft rays; scales small and cycloid; breast completely scaleless; lateral line arched over anterior half of pectoral fins, its posterior (straight) part with 41-43 scutes; caudal peduncle very slender, without bilateral keels above and below last lateral line scutes (Ref. 57392).
Coloration: back bluish, sides silvery; black spot on upper margin of gill cover; dorsal- and upper caudal-fin lobes broadly black-edged, other fins light; juveniles with 4-5 dark crossbars on back and sides (Ref. 57392).
Adults are found mainly in coastal areas, entering brackish water (Ref. 2683, 57392). Common mostly in midwater and near bottom (Ref. 7079). Young live in association with medusa (jellyfish) (Ref. 57392).
