Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 28.6, mean 27 °C (based on 364 cells).
Phylogenetic diversity index (Ref. 82805
= 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02570 (0.00978 - 0.06752), b=2.97 (2.75 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.25 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (18 of 100) .
