Burmese pythons eat small endangered animals like the mangrove fox squirrel, the Key Largo woodrat, the wood stork, and the Key Largo cotton mouse. Burmese pythons drastically reduce the number of non-endangered species like raccoons, opossums, white-tailed deer (yeah. They are fearsome hunters), and coyotes, which can have a negative effect on the health of the ecosystem as a whole. There is no snake in south Florida anywhere near as big or as effective a hunter as the python, so these animals do not see snakes as a threat and do not attempt evasive action. Burmese pythons compete for resources--very effectively--with endangered or vulnerable endemic species like the Florida panther, American crocodile, and many native snakes.
