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=0.01202 (0.00982 - 0.01472), b=3.07 (3.01 - 3.13), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisk nivå (Ref.
69278): 2.4 ±0.2 se; based on size and trophs of closest relatives
Resiliens (Ref.
