Estimates based on models
Preferred temperature (Ref.
123201): 5.4 - 14.4, mean 10.2 °C (based on 488 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00095 (0.00067 - 0.00137), b=2.95 (2.85 - 3.05), in cm total length, based on LWR estimates for this species (Ref.
