Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5645 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01950 (0.00951 - 0.03996), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.36 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
