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=0.00562 (0.00241 - 0.01314), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this Subfamily-BS (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (17 of 100).
