50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00730 - 0.02275), b=3.05 (2.90 - 3.20), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.0 ±0.37 se; Based on food items.
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
