50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00560 - 0.02463), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.8 ±0.2 se; based on size and trophs of closest relatives
Résilience (Ref.
