Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5098 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00196 - 0.01118), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.4 ±0.3 se; based on size and trophs of closest relatives
Resiliens (Ref.
