Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic. Tropical; 19°N - 9°N, 90°W - 78°W (Ref. 189)
Western Central Atlantic: Belize south to Panama and northeastern Colombia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm TL male/unsexed; (Ref. 5217); common length : 9.0 cm TL male/unsexed; (Ref. 5217)
soft rays: 18 - 22. Snout moderate, about 2/3 eye diameter; maxilla relatively long, tip bluntly rounded, reaching to and a little beyond front margin of pre-operculum; gill cover canals of panamensis type. Anal fin fairly long, its origin below about middle of dorsal fin base. A silver stripe along flank, less than eye diameter (Ref. 189). Upper surface of head and back with dusky punctuations: dark spots at base of anal, median dark line posterior to anal (Ref. 37032).
Found along beaches and in estuaries, lagoons or other brackish habitats, apparently able to tolerate a wide range of salinities, but perhaps not entering freshwater.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00247 - 0.01115), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±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 (13 of 100) .
