Etymology: Diapterus: Greek, di = two + Greek, pteron = wing, fin (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 9 - 70 m (Ref. 9626). Tropical; 35°N - 30°S, 97°W - 32°W
Western Atlantic: southern Gulf of Mexico, Central America and the Antilles to Brazil (Ref. 9626).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 13 - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 3722); common length : 30.0 cm TL male/unsexed; (Ref. 3722); max. published weight: 76.30 g (Ref. 118626)
Common in mangrove-lined lagoons; also found over shallow mud and sand grounds in marine areas. Juveniles common in hypersaline lagoons and in brackish water (Ref. 5217). Probably feeds on small benthic invertebrates. Marketed fresh but not highly esteemed. Minimum depth from Ref. 26912.

Estimates based on models
Preferred temperature (Ref. 115969
): 23.5 - 28, mean 26.5 °C (based on 288 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.01040 - 0.01455), b=3.01 (2.96 - 3.06), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.2 se; based on diet studies.
Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (18 of 100) .
