Wildlife researchers have found an unconventional way to help control invasive Burmese pythons in the Florida Everglades – by using one of the snakes’ favorite prey.
Opossums are a key food source for Burmese pythons, which are top predators in the Everglades and have established a permanent breeding population in South Florida, severely harming the ecosystem by wiping out native animals, according to the Conservancy of Southwest Florida.
In 2022, researchers discovered the new technique accidentally while studying the movements and behaviors of small mammals. The team had fitted GPS collars to opossums and raccoons on Florida's southern coast and discovered an added side effect: They could also track the enormous snakes after they swallowed the tagged animals whole, LiveScience reported.
"We need everything that we can find to remove as many pythons as possible," Michael Cove, one of the researchers and curator of mammals at the North Carolina Museum of Natural Sciences, told The South Florida Sun-Sentinel in 2023.
With that in mind, Cove, A.J. Sanjar and other researchers expanded the effort to track and euthanize invasive pythons as part of Florida’s conservation work. Here’s how they do it.
