Phylogenetic diversity index (संदर्भ 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00684 - 0.03506), b=2.86 (2.68 - 3.04), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (संदर्भ 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
लौटाव (संदर्भ 120179):  ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
