Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 27.3, mean 26.5 °C (based on 28 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00470 - 0.02937), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.31 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Price category (Ref. 80766): Unknown.
