Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00470 - 0.03074), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
مستوى غذائي (Ref.
69278): 3.9 ±0.7 se; based on size and trophs of closest relatives
المرونه (Ref.
