Estimates based on models
Preferred temperature (Ref.
123201): 1.7 - 3.5, mean 2.5 °C (based on 105 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (48 of 100).
