Estimates based on models
Preferred temperature (Ref. 123201): 23.2 - 28.2, mean 26.9 °C (based on 385 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.7539 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00144 - 0.00875), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.4 ±0.1 se; based on diet studies.
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).
