Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range - 50 m (Ref. 189), usually - m (Ref. ). Tropical; 0°C - ; 28°N - 5°N, 111°W - 77°W (Ref. 189)
Eastern Pacific: southern Gulf of California to Panama; perhaps extending to Colombia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm TL male/unsexed; (Ref. 96339)
soft rays: 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).

Estimates based on models
Preferred temperature (Ref. 115969
): 23.1 - 28.6, mean 27.5 °C (based on 30 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) .
