Estimates based on models

Preferred temperature (Ref. 123201 ): 27.3 - 29.1, mean 28.2 °C (based on 110 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.5   ±0.47 se; based on food items. Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
