Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00603 (0.00315 - 0.01154), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.5 se; based on diet studies.

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

Price category (Ref. 80766): Unknown.
