Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 46 - 50. Body moderately slender, belly with 23 to 25 + 11 to 14 scutes. Eye large, lower jaw projecting; gap between hind tip of premaxilla a ligament, not a toothed bone. Dorsal fin origin a little before midpoint of body; anal fin long, its origin below about last dorsal fin rays.
Occurs in coastal waters, entering estuaries, perhaps to spawn there (Ref. 9336). Feeds on planktonic crustaceans; larger individuals feed on shrimps (Ref. 9336). Flesh of low quality (Ref. 9336).
