Estimates based on models

Preferred temperature (Ref. 123201): 28 - 28.8, mean 28.5 °C (based on 18 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00183 - 0.00992), b=3.04 (2.83 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec=12).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Price category (Ref. 80766): High.
