Estimates based on models

Preferred temperature (Ref. 115969): 13.6 - 20.1, mean 18.3 °C (based on 34 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00141 - 0.00709), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±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):  Very high vulnerability (84 of 100) .
