Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 7.3, mean 3.1 °C (based on 17 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00408 - 0.02036), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.4 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): Low vulnerability (19 of 100).
