Marine; brackish; pelagic-neritic; depth range 1 - 22 m (Ref. 189). Tropical; 1°N - 27°S, 51°W - 32°W (Ref. 189)

Morphology | Morphometrics
soft rays: 22 - 25. Snout short, about 1/2 eye diameter; maxilla shorter than in most other Anchoa species, tip pointed, not reaching beyond hind margin of pre-operculum; gill cover canals of walkeri-type. Pectoral fins large, reaching about pelvic fin origin; anal fin fairly long, its origin below or just before midpoint of dorsal fin base. A silver stripe along flank, less than eye diameter.
Presumably schooling along beaches and down to 22 m. A single specimen was recorded from Coqueiros at the mouth of the Paraguaçu River, thus able to tolerate lowered salinities. More data needed.

Estimates based on models
Preferred temperature (Ref. 115969
): 22.5 - 28.2, mean 27.3 °C (based on 81 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00224 - 0.01119), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
