Estimates based on models

Preferred temperature (Ref. 123201): 23.2 - 29.2, mean 27.9 °C (based on 2328 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [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):  3.3   ±0.39 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
