Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00468 - 0.01175), b=3.10 (2.97 - 3.23), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Nível Trófico (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
