Estimates based on models
Preferred temperature (Ref.
123201): 13.3 - 28, mean 26.1 °C (based on 304 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00129 (0.00079 - 0.00211), b=3.05 (2.91 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.0 se; based on diet studies.
Resilience (Ref.
