Furthermore, predation on bats by amphibians is rare and infrequently documented in the literature (Mikula 2015). Herein, we report an event of bat predation by a Cuban Treefrog. In January 2016, we observed a large adult female Cuban Treefrog (nearly 130 mm SVL) eating a bat at dusk in a house at “Reparto Universitario” (22°26'00.05"N, -79°54'28.00"W; reference datum: WGS84), Santa Clara, Villa Clara Province, in central Cuba. The frog was on a concrete floor swallow- ing a bat headfirst (Fig. 2A); induced regurgitation (Fig. 2B) revealed an adult male Pallas’s Mastiff Bat (Molossus molossus, Molossidae; 12 g body mass). The lack of rigor mortis suggested Fig. 1. Adult female Cuban Treefrog (Osteopilus septentrionalis). that the bat probably was alive when captured by the frog. Photograph © C.A. Mancina.
