Estimates based on models

Preferred temperature (Ref. 123201): 23.4 - 28, mean 26.8 °C (based on 492 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00776 - 0.01949), b=3.01 (2.88 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.60 se; based on food items.
Generation time: 5.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
