Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00052 (0.00022 - 0.00126), b=3.13 (2.93 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 4.0 ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
