Estimates based on models
Preferred temperature (Ref.

Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00774 - 0.05639), b=3.03 (2.79 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
