Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 28.8, mean 27.6 °C (based on 504 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5049 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00163 - 0.00845), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
