Estimates based on models
Preferred temperature (Ref.
123201): 3.9 - 5.6, mean 4.6 °C (based on 4 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00511 - 0.02146), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100).
