EVERGLADES NATIONAL PARK, Florida (CNN) -- A family got quite a shock when an uninvited guest slithered into a picnic area in Florida.
They were visiting from Arkansas and captured a snake on camera.
The 17-foot Burmese python was killed by a park ranger.
In January, the Florida Fish and Wildlife Conservation Commission will host a 2013 Python Challenge. They hope it will help control the expanding population.
A grand prize of $1,500 will go to the person who kills the most pythons and a thousand dollars will go to the person who kills the longest python.
Researchers say pythons have devastated rabbit, fox, opossum and bobcat populations.
