= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00381 - 0.01901), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

).
Trophic level (Ref.
69278
): 3.9 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153
): Low to moderate vulnerability (34 of 100).
