Abstract

Preliminary quantitative information is given on the presence of barnacle cyprids and post-metamorphic stages in the diet of the molluscan grazer Chiton granosus Frembly 1827 (Mollusca: Placophora) sampled at Iquique, Chile. In December 2000, we observed the presence of barnacle cyprids and post-metamorphic stages at a high relative percentage of abundance (N = 30, 54,1% and 39,9%, respectively) and they were frequent in all of the individuals analyzed. Moreover, a high frequency of ocurrence of cyprid larvae (F% = 67) was recorded in the distal portion of the intestine; of these larvae, 15 were observed with signs of vital activity (appendage movement) in 45% of all the stomachs analyzed. Ingestion, of barnacle cyprids and post-metamorphic stages was observed at a high frequency throughout the five months of the study (N = 10, 96% ± 6,5 and 78% ± 23,6).
