Estimates based on models
Preferred temperature (Ref.
115969): 14.8 - 26, mean 16.6 °C (based on 31 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00240 (0.00108 - 0.00533), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
