Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
