Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00263 - 0.01321), b=3.02 (2.83 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.45 se; based on food items.
लौटाव (Ref. 120179):  ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Assuming fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
