Standing in front of a hissing, squirming 12-foot-long python Wednesday, Gov. Ron DeSantis said he’s doubling resources to remove the invasive species that’s destroying the natural food chain in Florida’s delicate Everglades. The state has been paying select hunters to catch and kill the invasive snakes on state lands since March 2017. Scientists say the giant constrictor snakes, which can grow over 20 feet (6 meters) long, have eliminated 99% of the native mammals in the Everglades, decimating food sources for native predators such as panthers and alligators.
