Estimates based on models
Preferred temperature (Ref.
123201): 3.8 - 5.3, mean 4.7 °C (based on 13 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00170 - 0.01121), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 4.1 ±0.1 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
