Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00278 - 0.01137), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Τροφικό Επίπεδο (Ref.
69278): 4.5 ±0.80 se; based on food items.
Ελαστικότητα (Ref.
