Estimates based on models
Preferred temperature (Ref.
123201): 23.8 - 28.8, mean 28 °C (based on 226 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00343 - 0.01604), b=3.17 (3.00 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Niveau trophique (Ref.
69278): 3.5 ±0.37 se; based on food items.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
