Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trofisch niveau (Ref.
69278): 2.0 ±0.0 se; based on diet studies.
Weerstandsvermogen (Ref.
