Environment / Climate / Range
Marine; freshwater; brackish; benthopelagic. Tropical; 19°N - 3°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 28.0 cm SL male/unsexed; (Ref. 11482)

soft rays: 8. This species is distinguished by having the following characters: pectoral fins short, usually reaching the vent, but not extending to the anal fin origin; upper and lower lips enlarged; 38-41 (mode 40) pored lateral-line scales; 12-13 (mode 12) gill rakers on the lower limb of the first branchial arch; 2nd anal spine when depressed extends to base of last anal ray or half the length of the caudal peduncle (Ref. 94655).
Eastern Central Pacific: Mexico to northern Peru.
Inhabits coastal waters and lagoons (Ref. 9303); on muddy or sandy bottoms to depths of 30 m and penetrates freshwater habitats in Mexico and Central America (Ref. 94655).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00747 - 0.03689), b=2.99 (2.80 - 3.18), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
