Estimates based on models

Preferred temperature (Ref. 123201): 27.9 - 29.1, mean 28.5 °C (based on 98 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00578 - 0.03452), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

營養階層 (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

回復力 (Ref. 120179): 低的, 最小族群倍增時間4.5 - 14 年 (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
