Estimates based on models
Preferred temperature (Ref.
123201): -1.2 - 1.2, mean 0.8 °C (based on 25 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00120 (0.00057 - 0.00252), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary K or Fecundity.).
