= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00206 - 0.00971), b=3.07 (2.89 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
