Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01485 - 0.05350), b=3.03 (2.87 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

Trophic level (Ref.
69278): 2.5 ±0.20 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
