50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00194 - 0.01077), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
