Estimates based on models
Preferred temperature (Ref.
123201): 28 - 29.3, mean 28.9 °C (based on 733 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00480 - 0.00690), b=3.14 (3.09 - 3.19), in cm total length, based on LWR estimates for this species (Ref.
