“…There are observations of bat catching by frogs when bat foraged very close to the ground surface (Torres 2013), near roosting places of bats such as caves (Means 2000(Means , 2003Cray 2007;Richards & Hall 2012) or consuming them in the vicinity of buildings (Petris 2011;Srpimentelbio 2015). Many bat species were, however, attacked when caught in mist nets; several frugivorous and nectarivorous bats, otherwise presumably immune to predation by amphibians, were thus attacked (Carollia perspicillata and Anoura caudifer, Glossophaga soricina, Lonchophylla mordax) (Ésberard et al 2006;Castro et al 2011;Filho et al 2014). Majority of bat catches involved larger and considerably opportunistic frog species.…”

Although bats (Chiroptera) belong to the most diverse mammalian orders, study of diversity of their natural predators has been seriously neglected for a long time. While some recent reviews contain comprehensive overviews of our recent knowledge on these phenomena for some animal groups, such work is still lacking for anamniotes - fishes and amphibians. Here, I am summarising bat predation incidences by anamniotes that were published in scientific journals and public web domains. I found out that at least 14 species of fishes and 14 species of frogs were observed as feeding on bats. Moreover, 7 and 16 species of bats were recorded as victims of hunting activity of fishes and frogs, respectively. Majority of localised incidences came from the New World; frog (between latitude 49°N to 28°S) attacks were distributed mainly in tropical or subtropical areas < 30° from equator (70% of all records), fish (44°N to 20°S) incidences reach same proportion in colder areas (> 30° from equator) and warmer areas. In some cases, these predators can regularly feed on bats, especially when hunting near roosting places of bats; however, with respect to number of recorded cases (21 for fishes and 37 for amphibians), bat predation by anamniotes seems to be very rare and opportunistic with only very limited influence on bat populations or their behaviour.

“…forest in Bolivia (Heyer, 2005;Jansen and Schulze, 2012;de Sá et al, 2014). This species mainly feeds on arthropods and small vertebrates (e.g., frogs and bats; Santana et al, 2012;Leite Filho et al, 2014;Caldas et al, 2019). Herein we report for the first time a predation on the endemic leptodactylid Rupirana cardosoi Heyer, 1999 by a juvenile L. vastus in Bahia state, Brazil, and provide a prey items compilation for L. vastus.…”

“…species present in the same habitat), whereas hylids are often found on a higher vegetal strata, but occasionally forage on the ground and might be opportunistically preyed (Haddad et al, 2013). As for bats, reports show that L. vastus actively preyed on bats trapped into mist nets (see Leite Filho et al, 2014) or positioned themselves near a cave entrance and waited for fallen bats that collided with the narrow entrance (see Gouveia et al, 2009). Our survey reinforces L. vastus as a generalist and opportunistic predator (Santana et al, 2012) of small vertebrates and arthropods (Teles et al, 2017;Caldas et al, 2019).…”

Leptodactylus vastus (LEPTODACTYLIDAE) predation on an endemic frog, and a compilation of its diet

et al. 2021

Diet composition constitutes basic information on the natural history of the species. Despite the amount of data acquired in the last years, much remains to be known specially for geographically widespread species. Here we compiled the available dietary items of Leptodactylus vastus and report the first predation event upon Rupirana cardosoi by a juvenile L. vastus. The fact these species are syntopic in the region probably resulted in this novel predation event. Different from previous L. vastus predation observations, the specimens we observed do not present a striking difference in body size, but L. vastus was able to almost swallow L. cardosoi, coherent with findings that mouth size is related to prey selection in anurans. Also, our literature review showed that L. vastus is a generalist and opportunistic predator, that prey upon small vertebrates (Amphibia, Squamata, and Mammalia).
