Estimates based on models

Preferred temperature (Ref. 123201): 28.3 - 29.3, mean 28.8 °C (based on 1122 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
