Estimates based on models

Preferred temperature (Ref. 123201): 26.1 - 26.9, mean 26.7 °C (based on 39 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Assuming Fec < 10).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
