= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00256 - 0.01487), b=3.02 (2.85 - 3.19), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
