Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00358 - 0.02025), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

營養階層 (Ref.
69278): 3.3 ±0.43 se; based on food items.
Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
