Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00157 - 0.00764), b=3.19 (3.00 - 3.38), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.9 ±0.25 se; Based on food items.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Very high vulnerability (78 of 100) .

Price category (Ref. 80766): Unknown.
