= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

).
Trophic level (Ref.
69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Fishing Vulnerability (Ref.
59153
): Low vulnerability (10 of 100).
