Eating on the Rock Paintings: Diet Composition of Leptodactylus syphax Bokermann, 1969 in the Serra da Capivara National Park, Brazil

A new study reveals that the frog species Leptodactylus syphax in Brazil's Serra da Capivara National Park is a generalist and opportunistic predator, with no significant dietary differences between males and females. Researchers analyzed stomach contents of 16 individuals during the rainy season (January–May 2024), identifying 212 prey items across 16 categories, including Blattaria, Coleoptera, and Hymenoptera (Formicidae) as dominant. Plant fragments were also detected in nine individuals, suggesting a varied diet. The study highlights this species' active foraging strategy and contributes to the limited knowledge of leptodactylid feeding habits.
