Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6289 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00329 - 0.01007), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 4.5 ±0.80 se; based on food items.
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (29 of 100).
