Estimates based on models
Preferred temperature (Ref.
123201): 5.9 - 12.8, mean 8.3 °C (based on 194 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00831 - 0.04576), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.87 se; based on food items.
Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
लौटाव (Ref.
