Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00076 (0.00029 - 0.00197), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.5 ±0.8 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (73 of 100).
