50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Nível Trófico (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
