Short description

Dorsal spines (total): 11; Dorsal soft rays (total): 29-34; Anal spines: 2; Anal soft rays: 6. Diagnosis: medium-sized fish, fusiform and compressed; head short; eyes rather large; snout short; mouth large and oblique, subterminal; teeth villiform, set in narrow bands in both jaws; 5 marginal pores on snout and 6 mental pores; gill rakers long and slender, longer than gill filaments at angle of first gill arch; dorsal fin long, deeply notched; 2nd anal fin spine very strong, about as long as 1st soft ray and comprised less than twice in head length; caudal fin more or less pointed; scales ctenoid on body, cycloid on breast and head; lateral line extending to hind margin of caudal fin; swim bladder carrot-shaped, its front end with a pair of appendages subdividing into a group of short anterior branches and a bundle of 5-6 slender tubes extending backwards over half the length of swim bladder (Ref. 57396). Coloration: back olivaceous brown, sides silvery with series of dark dots, belly light, yellowish during reproduction period; spinous part of dorsal fin dark, soft part lighter, with 2-3 longitudinal series of dark dots; pelvics and anal fin yellowish (Ref. 57396).

Biology     Glossary (e.g. epibenthic)

Found in coastal waters over mud bottom (Ref. 3593, 57396), very close to the shore (Ref. 57396). Also enters estuaries and coastal lagoons (Ref. 3593), where reproduction takes place (Ref. 57396). Moves farther offshore to about 100 m for spawning during rainy season from December to February; Feeds on fish and shrimps (Ref. 28587).

IUCN Red List Status (Ref. 115185)
