Estimates of some properties based on models

Preferred temperature (Ref. 115969): 24.6 - 29.3, mean 28.5 (based on 2833 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5234   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00198 - 0.01270), b=3.05 (2.83 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.6 se; Based on size and trophs of closest relatives
Resilienza (Ref. 69278):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (86 of 100) .
