50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00000 (0.00000 - 0.00000), b=0.00000 (0.00000 - 0.00000), based on (Ref.

Trophic Level (Ref.
69278): 3.5 ±0.6 se; Based on diet studies.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).
Vulnerability (Ref.
