50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (-0.17356 - 0.18017), b=3.20951 (3.11124 - 3.30779), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 4.5 ±0.80 se; Based on food items.
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
