Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic; depth range 0 - 50 m (Ref. 189). Tropical; 10°N - 5°N, 82°W - 77°W (Ref. 189)
Eastern Central Pacific: Panama Bay.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.7 cm TL male/unsexed; (Ref. 114986); max. published weight: 49.80 g (Ref. 114986)
soft rays: 28 - 35. Body somewhat compressed, moderately deep. Snout pointed, about 1/2 to 3/4 eye diameter; maxilla moderate, tip somewhat bluntly pointed, reaching to middle of inter-operculum; gill cover canals of panamensis-type. Anal fin long, its origin under or slightly before dorsal fin origin. A narrow silver stripe along flank, about pupil diameter.
Occurs in coastal waters, probably tolerating lowered salinities (as in A. mundeola). More data needed.

Estimates based on models
Preferred temperature (Ref. 115969
): 27 - 28.1, mean 27.9 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00271 - 0.00885), b=3.16 (3.01 - 3.31), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.4 se; based on size and trophs of closest relatives
Generation time: 0.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=2.78).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
