FILE – In this Jan. 17, 2013, file photo, a captured 13-foot-long Burmese python is displayed for snake hunters and the media before heading out in airboats for the Python Challenge in the Florida Everglades. An appeals court ruled the federal government cannot legally stop trade of Burmese pythons and other giant exotic snakes within the continental U.S. However, snake owners are cautioned not to move their reptiles just yet, as other legal challenges may remain. The U.S. Fish and Wildlife Service is reviewing the ruling. (AP/RSS Photo/J Pat Carter, File)
