Estimates based on models
Preferred temperature (Ref.
115969): 26.8 - 29.1, mean 28.2 °C (based on 129 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00437 - 0.01096), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for species & Genus-BS (Ref.
93245).
Trophic level (Ref.
