Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00486 - 0.02155), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.7   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100). 🛈
