Estimates based on models

Preferred temperature (Ref. 115969): 25.5 - 29.3, mean 28.6 °C (based on 1556 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00261 - 0.01268), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
