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=0.01000 (0.00376 - 0.02663), b=3.07 (2.84 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.9 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
