The growth of Plicopurpura columellaris has been described using the von Bertalanffy growth model, assuming asymptotic growth. In the present study, a growth analysis was conducted using the five cases of Schnute's model to determine the type of growth P. colummellaris exhibits. Length frequency data for males and females, collected between September 2000 and December 2001 at six sites in the rocky intertidal of Guerrero, Mexico, were analyzed. Five cases of the Schnute model were estimated for males and females, and according to the bias-corrected Akaike information criterion (AICc), case 2 with two parameters best describes growth in males (
