): PD
50
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00229 - 0.01150), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

).
Trophic level (Ref.
69278
): 2.9 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153
): Low vulnerability (10 of 100).
