<P> Burmese pythons prey on a wide variety of birds , mammals , and crocodilian species occupying the Everglades . Pronounced declines in a number of mammalian species have coincided spatially and temporally with the proliferation of pythons in southern Florida , indicating the already devastating impacts upon native animals . Although the low detectability of pythons makes population estimates difficult , most researchers propose that at least 30,000 and upwards of 300,000 pythons likely occupy southern Florida and that this population will only continue to grow . The importation of Burmese pythons was banned in the United States in January 2012 by the U.S. Department of the Interior . </P>
