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=0.00372 (0.00198 - 0.00699), b=3.24 (3.07 - 3.41), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.7 ±0.4 se; Based on size and trophs of closest relatives

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

Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100) .

Price category (Ref. 80766): Unknown.
