Estimates based on models

Preferred temperature (Ref. 115969): 24.9 - 29.1, mean 26.7 (based on 229 cells).

Índice de diversidade filogenética (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).

Nível Trófico (Ref. 69278): 3.1 ±0.5 se; based on size and trophs of closest relatives

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