Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00603 - 0.01658), b=3.01 (2.87 - 3.15), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref.

Trophic level (Ref.
69278): 3.7 ±0.57 se; based on food items.
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
