Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Prijsklasse (Ref. 80766): Unknown.
