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=0.00316 (0.00169 - 0.00592), b=3.19 (3.02 - 3.36), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.7 ±0.54 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (K=0.077; tmax=38; Fec = 458 (per batch)).

Vulnerability (Ref. 59153): High to very high vulnerability (70 of 100) .

Price category (Ref. 80766): Unknown.
