The knowledge about interactions between predators and prey is essential for understanding the natural history of animals, especially snakes, which are cryptic organisms that are difficult to visualize in the wild. This article reports on the predation of lizards, frogs, bats and venomous snakes by the snake Philodryas nattereri, evidencing its generalist feeding habits.
Tropidurus hispidus is a member of the Tropiduridae family and presents a wide distribution in Northeastern Brazil (Abreu et al. 2002.). It is a diurnal, heliophilous, generalist, and abundant species (Vitt et al. 1996) and is mainly observed in rocky outcrops, trunks, and man-made structures (Rodrigues 1987, Carvalho 2013. Herein, we report two cases of tail bifurcation in Tropidurus hispidus. On the 3rd September 2017 at 0839 h in an area of Caatinga, in a rural property named Sítio Fechado, (7° 20' 45'' S/37° 17' 20'' W; 737 m.a.s.l) in the municipality of Brejinho, Pernambuco State,Northeastern Brazil, we sighted an adult T. hispidus female presenting a bifurcated tail, on the wall of a residence (Figure 1). The second sighting was recorded on the 24th September 2019 at 1150h, during a behavioral study of this species (primary author), we observed one second female presenting a small tail bifurcation, during a mating encounter (Figure 2). Lizards have a remarkable ability to repair various tissues, such as muscle, osteological and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
