Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 14-17; Épines anales 0; Rayons mous anaux: 45 - 50; Vertèbres: 42 - 43. Diagnosis: Body moderately deep, compressed, belly with a sharp and serrated keel of scutes from gill opening to anus, 25-27 pre-pelvic and 6-8 post-pelvic sharp scutes (Ref. 187, 188, 81270). Eye large, mouth pointing upwards, lower jaw projecting (Ref. 187, 188). Dorsal fin at or before midpoint of body; anal fin long, with more than 40 finrays, its origin below dorsal fin base; pelvic fins small (Ref. 187, 188). Swimbladder with two short tubes passing back in the muscles on either side of haemal spines (Ref. 188). Other clupeoid fishes in the area are more slender, have a much shorter anal fin and the lower jaw is not strongly projecting (Ref. 188).

Biologie     Glossaire (ex. epibenthic)

Found in the marine environment, pelagic, along beaches and just off shore, down to about 25 m, also in lagoons and estuaries, penetrating into almost freshwater (Ref. 187, 188, 54448). A marine migrant (Ref. 117399). Rarely found below 35 m depth (Ref. 86940). It feeds on small planktonic animals, e.g. small fish and crustaceans; it doesn't seem to feed on plankton (Ref. 188, 3166, 47405).
