Estimates based on models

Preferred temperature (Ref. 123201): 28 - 29.5, mean 28.9 °C (based on 451 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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): 3.3 ±0.5 se; based on size and trophs of closest relatives

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