Python molurus
Due in part to its prevalence in the exotic pet trade, Florida has a large number of non-native species. The Florida Fish and Wildlife Commission tracks 31 species of mammals, 196 species of birds, 48 species of reptiles, 4 species of amphibians, and 55 species of fish that have been observed in the state. Many of the identified species are either non-breeding or stable populations, but several species, including the cane toad ("Bufo marinus"), Gambian pouched rat ("Cricetomys gambianus"), Nile monitor ("Varanus niloticus"), and Burmese python ("Python molurus bivittatus"), have created significant impact on the delicate ecosystems of the state, especially in the tropical southern third of the state.
