Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00228 - 0.01266), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.1 ±0.4 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.).
