Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.01562 - 0.02435), b=3.01 (2.96 - 3.06), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 2.6 ±0.26 se; based on food items.
Resilience (Ref.
