Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00285 - 0.01396), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 4.5 ±0.80 se; based on food items.
Resiliens (Ref.
120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High vulnerability (60 of 100).
