Eastern Atlantic: west African coast, from Guinea to Congo (Ref. 57394). Also reported from Senegal (Ref. 4323, 28587, 33587), Gambia (Ref. 5476), Guinea-Bissau (Ref. 26999) and as far south as Angola (Ref. 3166).
Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm 38.8, range 7 - ? cm
Max length : 20.0 cm TL macho/indeterminado; (Ref. 57394); common length : 15.0 cm TL macho/indeterminado; (Ref. 2683)
Espinhos dorsais (total): 9; Raios dorsais moles (total): 10; Espinhos anais 3; Raios anais moles: 8. Diagnosis: body oblong and compressed; snout pointed, shorter than eye diameter; mouth strongly protrusible; nostrils contiguous, situated at midpoint between eye and snout tip; dorsal fin deeply notched; pectoral fins long, reaching to, or extending beyond anal-fin origin; large cycloid scales; scales of the interocular space not reaching anterior border of eyes; spinous part of dorsal fin greyish, without a black spot at tip (Ref. 57394).
Coloration: back olivaceous-brown, sides silvery, with longitudinal dark bands; young individuals with narrow, dark vertical bars on sides; spinous part of dorsal fin distally greyish, but without a distinct black spot at tip; juveniles with 2 longitudinal series of dark spots on dorsal fin (Ref. 57394).
Occurs on littoral mud and sand bottoms to about 60 m depth (Ref. 57394). Often enters estuaries and coastal lagoons (Ref. 7375) during reproduction (Ref. 57394). Feeds on fish, shrimps, mollusks, plankton and detritus (Ref. 28587).
