Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00374 - 0.01688), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.6 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
