Estimates based on models
Phylogenetic diversity index (Ref.

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00391 - 0.02557), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Niveau trophique (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
