Phylogenetic diversity index (Ref. 82804
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01107 - 0.04526), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.2 se; based on diet studies.
Resilience (Ref. 120179
