Widespread occurrence of the American Bullfrog, Lithobates catesbeianus (Shaw, 1802) (Anura: Ranidae), in Brazil

We report new records of Lithobates catesbeianus feral populations in Brazil. Data were based on fieldwork, natural history collection records, and literature and electronic database searches. Lithobates catesbeianus occurs in 130 municipalities of Brazil, including 55 presented for the first time in this work. Most records are from south and southeastern Brazil in the Atlantic Forest biome with climatic conditions that are favorable to the establishment of bullfrog populations. The wide and possibly expanding distribution of feral L. catesbeianus populations in Brazil poses a major conservation challenge and demands research on the invasion patterns
