Estimates based on models

Preferred temperature (Ref. 123201): 18.8 - 25.9, mean 23.2 °C (based on 117 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00877 - 0.02613), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  2.0   ±0.00 se; based on food items.
Generation time: 4.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
