Bayesian length-weight: a=0.00813 (0.00354 - 0.01865), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.48 se; based on food items.
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).
