Estimates based on models

Preferred temperature (Ref. 123201): 15.9 - 25.2, mean 20.8 °C (based on 20 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5029   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00157 - 0.00767), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.9   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec=2).
