Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00292 - 0.01304), b=3.19 (3.01 - 3.37), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Tmax=8; k=0.18; Fec=20,000).
Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100) .
