Estimates based on models

Preferred temperature (Ref. 115969): 17.5 - 23.6, mean 20.2 °C (based on 66 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (0.00170 - 0.00646), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
