Estimates based on models
Preferred temperature (Ref.
123201): 11.5 - 23.5, mean 17.7 °C (based on 364 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00621 - 0.01402), b=2.88 (2.77 - 2.99), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
