ABSTRACT Several bat species use caves as roosts and some of these caves can harbor high concentrations of individuals.Such caves may represent opportunities for certain predators, benefiting from the concentration of potential prey.Here, we report the predation of a Pteronotus bat by a Corallus hortulanus Hats in the Brazilian Amazon.On three occa
