Bayesian length-weight: a=0.00832 (0.00318 - 0.02175), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.2 ±0.45 se; based on food items.
Generation time: 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
