Estimates based on models

Preferred temperature (Ref. 123201): 21.8 - 28, mean 26.4 °C (based on 332 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02754 (0.01730 - 0.04384), b=2.89 (2.76 - 3.02), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.4   ±0.2 se; based on diet studies.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
