Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00760 - 0.03623), b=2.90 (2.71 - 3.09), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.0 ±0.4 se; Based on size and trophs of closest relatives
Resilienza (Ref.
69278): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
