50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00155 - 0.00774), b=3.10 (2.90 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic Level (Ref.
69278): 3.9 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref.
