Estimates based on models
Preferred temperature (Ref.
123201): 17.1 - 20.6, mean 19.7 °C (based on 17 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6875 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.59 se; based on food items.
Generation time: 5.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
