Estimates based on models

Preferred temperature (Ref. 115969): 24.7 - 28.9, mean 27.7 °C (based on 392 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.01067 - 0.04484), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.1 se; based on diet studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
