Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 16 - 19. Body slender. Snout moderate, about 3/4 eye diameter; maxilla rather long, tip pointed, reaching to or almost to edge of gill cover; gill cover canals of walkeri-type. Anal fin short, its origin below or a little before midpoint of dorsal fin base. A silver stripe along flank, less than eye diameter.
Pelagic, nearshore (Ref. 96339). Occurs in coastal waters (Ref. 189). Probably not entering estuaries (Ref. 189).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00232 - 0.01135), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
