Estimates based on models

Preferred temperature (Ref. 115969): 1.7 - 8.2, mean 6.9 (based on 11 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00119 - 0.00554), b=3.19 (3.00 - 3.38), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.3   ±0.3 se; Based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High to very high vulnerability (68 of 100) .
