Introduction: Trophic interactions between fishermen and fish bats are common and most of the times the bat is the predator and fish, the prey. However, so far they have not been registered opposite events. Methods: During a sampling sesion of fish in the the river basin of La Vieja, high Cauca (Colombia) in 2009, a toad catfish Pseudopimelodus schultzi was captured and after stomach analysis, an individual of the bat Noctilio leporinus was found. Results and discussion: We report the first event of predation of N. albiventris by P. schultzi. This finding may have three possible explanations: 1) Opportunistic predation. 2) Active predation or 3) Opportunistic consumption.
