50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00437 - 0.01992), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Niveau trophique (Ref.
69278): 2.8 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
