Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5003 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
