Abstract

Saurophagy constitutes an important source of mortality among lizards and has been reported for the genus Tropidurus. However, the extension of this behavior remains unknown. Herein, we record the predation of T. jaguaribanus by its congener T. hispidus. This is the first report of saurophagy among different species of syntopicTropidurus. Furthermore, whereas published records of saurophagy tend to be directed against juveniles, this case involved two adult individuals.A saurofagia constitui uma importante fonte de mortalidade entre lagartos e tem sido reportada para o gênero Tropidurus. Contudo, a extensão deste comportamento permanece desconhecida. Neste estudo registramos a predação de T. jaguaribanus por seu congênere T. hispidus. Este é o primeiro caso de saurofagia entre diferentes espécies de Tropidurus sintópicos. Além disso, embora a saurofagia tenda a ser direcionada contra jovens, este caso envolveu dois indivíduos adultos.
