Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01134 - 0.04848), b=2.96 (2.78 - 3.14), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.28 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Fec=32,000 (from an egg cluster)).
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
Price category (Ref. 80766):   Medium.
