Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.

Trofisch niveau (Ref.
69278): 2.0 ±0.1 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
