Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804): PD₅₀ = 0.7656 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00240 - 0.00955), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Fonte Biblio. 69278): 2.0 ±0.00 se; based on food items.

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100). 🛈
