Estimates based on models
Preferred temperature (Ref.
123201): 1.3 - 2.9, mean 2.1 °C (based on 75 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00171 - 0.01116), b=3.11 (2.89 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Resilienza (Ref.
