%X the diet of chaetognath species were studied by examining the gut contents of 9466 specimens collected off ubatuba region, sŁżo paulo state. the greatest proportion of chaetognaths (7119 individuals) showed their gut contents empty. copepods, mollusc eggs, appendicularians, cladocerans and annelids were the most common food items in the gut contents of juveniles and mature stages. cannibalism occurred in low frequency. in summer the copepods temora stylifera and paracalanus spp were more abundant, whereas oncaea spp and mollusc eggs were heavily preyed in winter. there was a clear trend of increasing prey size with the developmental stage.
