Estimates based on models
Preferred temperature (Ref. 115969
): 26.7 - 28.9, mean 28 °C (based on 244 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00071 (0.00034 - 0.00147), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.60 se; based on food items.
Resilience (Ref. 120179
