Environment / Climate / Range Ecology

Freshwater; pelagic.   Tropical; 7°N - 2°S

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 3.5 cm SL male/unsexed; (Ref. 188)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12-18; Anal spines: 0; Anal soft rays: 16 - 27. Pre- and post-pelvic scutes lacking (pelvic scute present, tips of its lateral arms bifurcated). Jaws about equal, with fine teeth; no second supra-maxilla; branchiostegal rays 3 or 4. Scales large. Occurs with other pellonulines, but the smoothly rounded belly, absence of spiny post-pelvic scutes and lack of a second supra-maxilla makes it unmistakable.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00456 - 0.02002), b=3.05 (2.88 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.47 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Low.
