Estimates based on models
Preferred temperature (Ref.
123201): 12.4 - 15.1, mean 14.3 °C (based on 2075 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00400 - 0.02282), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
