Abstract

We recorded two tadpoles of Leptodactylus troglodytes eating Physalaemus albifrons eggs in a semiarid area located in the state of Bahia, Brazil. The oophagous tadpoles were in stage 37 (Gosner, 1960). One of them contained 458 eggs in its intestinal tract and its width was 71% larger than other L. troglodytes tadpoles not observed eating eggs. Tadpoles developing in habitats subjet to water stress may supplement their diets with alternative foods and adopt facultative oophagy. Tadpoles of L. troglodytes probably are oophagic opportunists and they may also consume eggs of other species besides P. albifrons.
