Estimates based on models
Preferred temperature (Ref.
115969): 1.2 - 6.9, mean 3.6 °C (based on 326 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.7539 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00445 - 0.02704), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.1 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100) .
