Estimates based on models
Preferred temperature (Ref.
123201): 9.3 - 15.2, mean 12.6 °C (based on 12 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5044 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00247 - 0.01115), b=3.21 (3.01 - 3.41), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

Niveau trophique (Ref.
69278): 3.6 ±0.3 se; based on size and trophs of closest relatives
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
