Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00234 - 0.01075), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tmax=3).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
