Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Assuming Fec. <10; tm=1.8; K=0.3 (in captivity).).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100) .
Price category (Ref. 80766):   Medium.
