					Phylogenetic diversity index  (Ref.

50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].					
													Bayesian length-weight: a=0.01072 (0.00469 - 0.02447), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

					Trophic level  (Ref. 
69278):  2.6   ±0.2 se; based on size and trophs of closest relatives					
											
				
				
										
						Resilience  (Ref. 
120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).					
											
				
									
					Fishing Vulnerability  (Ref.
