Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00282 - 0.02948), b=3.05 (2.79 - 3.31), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  .
Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100) .
Price category (Ref. 80766):   Unknown.
