Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5315 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00191 (0.00071 - 0.00512), b=3.13 (2.90 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 4.3 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Very Low, minimum population doubling time more than 14 years ().
Vulnerability (Ref.
59153): Very high vulnerability (90 of 100) .
