50 = 0.6270 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.1 ±0.0 se; based on diet studies.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
