Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00434 - 0.01593), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

Nível Trófico (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref.
