Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.4 se; based on size and trophs of closest relatives

جهندگی (Ref. 120179): خیلی آهسته, كمينه زمان لازم براي دو برابر شدن جمعيت بيش از 14 سال (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
