Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 55763); common length : 7.0 cm TL male/unsexed; (Ref. 55763)
soft rays: 24 - 29. Body moderately elongate. Snout moderate, about 3/4 eye diameter; maxilla moderate, tip pointed, reaching onto inter-operculum, but not to edge of gill cover; gill cover canals of panamensis-type. Anal fin fairly long, its origin before midpoint of dorsal fin base. A narrow silver stripe along flank, about 1/2 eye diameter.
Occurs in coastal waters. In the Gulf of Nicoya, Costa Rica it was recorded only in the more oceanic outer part of the Gulf, along sandy beaches.

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 28.6, mean 27.8 °C (based on 16 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00232 - 0.01135), b=3.14 (2.97 - 3.31), 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) .
