Cave environments are characterized by a scarcity of available organic material, little or no primary production, and low or absent natural light (Culver and Pipan, 2019). Additionally, they have high environmental stability with temperatures close to the annual external average, humidity tending to saturation, and simplified trophic networks (Barr, 1968). However, ecological interactions and predation networks in neotropical caves are still understudied (Souza-Silva and Ferreira, 2014; Resende and Bichuette; 2016, Bernardi et al., 2020). Frogs are among the food items of top predator invertebrates (Toledo, 2005; Barbo et al., 2009; Sanches et al., 2018). In caves, spiders are among the top predators (Bernardi et al., 2020) and represent a group of significant diversity compared to other subterranean animal groups (Trajano and Bichuette, 2010; Cizauskas, 2017). However, there are gaps in our understanding of behavioural and ecological interactions in cave habitats.
