We examined the diet for four eyes toad (Pleurodema thaul) in Hualpén (Talcahuano, Chile). The study was carried out during the breeding season (June - December) in 2000 and 2001. These anurans consume fewer preys during the breeding season, and they present a low occurrence frequency (50.63%). The results show the P. thaul diet include for arthropods (IRI = 0.92), with a lower consumption of vegetables (IRI = 0.035). We determined a high diversity of prey, with 37 taxa of invertebrates. The alimentary items dipteral and arachnids are the most common. No relationships occurred between the size of the preys and the size of the anurans
