Estimates based on models

Preferred temperature (Ref. 123201): 14.1 - 23.8, mean 19.3 °C (based on 180 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
