Preferred temperature (Ref. 123201
): 22.3 - 29.1, mean 26.9 °C (based on 255 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00049 (0.00024 - 0.00100), b=3.26 (3.10 - 3.42), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.56 se; based on food items.
Resilience (Ref. 120179
