Estimates based on models

Preferred temperature (Ref. 123201): 21.4 - 28, mean 27.1 °C (based on 208 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00089 (0.00039 - 0.00204), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives
