Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5098 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00196 - 0.01118), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 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 (13 of 100).
