Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00294 - 0.01293), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Nível Trófico (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
