Estimates based on models

Preferred temperature (Ref. 123201): 9.7 - 27, mean 20.2 °C (based on 252 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00183 - 0.00992), b=3.04 (2.83 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.4 se; based on diet studies.

جهندگی (Ref. 120179): خیلی آهسته, كمينه زمان لازم براي دو برابر شدن جمعيت بيش از 14 سال (Fec=8).
