Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00242 - 0.01036), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
