This species has spots on sides smaller than scales, aligned in about 15 regular series (vs. not clearly aligned); abdomen predominantly whitish or greyish in life (similar to R. gemmata, vs. reddish in R. ocotal; ventral angle of articular is acute (vs. right); the first neural spine oriented rostrad (vs. caudad); circumpeduncular scales as few as 17 (vs. always more than 19); distance from the caudal esophageal loop in gut to esophagus always greater than 24% gut length (vs. less than 16%) (Ref. 74403). There are no unique autapomorphies.

Biologia     Glossário (p.ex. epibenthic)

Occurs in swampy areas with warm, murky water. Found in weedy, mud-bottomed and sand-bottomed canals and drainage ditches (Ref. 5723). Prefers coastal plains and slow moving waters of the lower river valleys (Ref. 7335). Feeds on worms, crustaceans, insects and fish (Ref. 7020).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02692 (0.01216 - 0.05956), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.5   ±0.51 se; based on food items.
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (Assuming tm<1 and multiple annual spawning; Fec=500-800).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
Nutrients (Ref. 124155):  Calcium = 121 [59, 208] mg/100g; Iron = 1.29 [0.71, 2.55] mg/100g; Protein = 18.1 [16.6, 19.6] %; Omega3 = 0.388 [0.142, 1.132] g/100g; Selenium = 72.5 [27.5, 166.3] μg/100g; VitaminA = 36.3 [9.2, 117.9] μg/100g; Zinc = 1.66 [1.07, 2.56] mg/100g (wet weight);
