Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5098 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00246 - 0.01172), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.3 se; based on size and trophs of closest relatives
Generation time: 3.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
