Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00888 (-0.21703 - 0.23479), b=3.24241 (3.12004 - 3.36478), based on LWR estimates for this family-BS (Ref.

Trophic Level (Ref.
69278): 2.9 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
