Despite experts\u2019 best attempts to <a href=\"https:\/\/www.popsci.com\/environment\/eat-invasive-species\/\" target=\"_blank\" rel=\"nofollow noopener\">highlight their nutritional value<\/a> and even hunt them <a href=\"https:\/\/www.popsci.com\/environment\/robot-bunnies-florida-invasive-pythons\/\" target=\"_blank\" rel=\"nofollow noopener\">using robotic rabbits<\/a>, the snakes have continued to decimate native animal populations, since they were introduced into the Everglades during the 1970s.<\/p>\n<p class=\"article-paragraph skip\">Curtailing Florida\u2019s unwanted apex predators is much easier said than done. Burmese pythons can grow upwards of 20-feet-long, and unlike humans, they are the species that is specifically evolved to thrive in subtropical wetlands. Local opossums, on the other hand, don\u2019t have any problem traipsing through the marshy terrain the way we do.<\/p>\n<p class=\"article-paragraph skip\">In 2022, <a href=\"https:\/\/naturalsciences.org\/\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">North Carolina Museum of Natural Sciences<\/a> wildlife biologists <a href=\"https:\/\/2025midwestfw.sched.com\/speaker\/arya_sanjar.27hsi56o\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">A.J. Sanjar<\/a> and <a href=\"https:\/\/naturalsciences.org\/staff\/michael-cove\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">Michael Cove<\/a> traveled to Florida to survey the habits of opossums after fitting them with tracking collars. It didn\u2019t take long before they ran into a problem: local pythons kept eating their study participants. Each felled opossum wasn\u2019t only a lost source of information\u2014it was expensive, too. At the time, each tracking collar cost about $1,500.\u00a0<\/p>\n<p class=\"article-paragraph skip\">While the issue was annoying, it also prompted an interesting discussion. The pythons that ate the opossums were all euthanized as part of Florida\u2019s conservation efforts. What if researchers intentionally deployed opossums with (much cheaper) tracking collars, then used them as bait for thinning python numbers?<\/p>\n<p class=\"article-paragraph skip\">After a few years of tinkering with the plan and securing additional funding including $190 collars, Sanjar and Cove are planning to use Crocodile Lake National Wildlife Refuge in Key Largo for their new opossum vs. python experiment. According to the <a href=\"https:\/\/cbs12.com\/news\/local\/possums-vs-pythons-how-floridas-only-marsupial-became-a-weapon-against-invasive-snakes\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">South Florida Sun Sentinel<\/a>, the researchers aim to enlist at least 40 opossums by later this summer. Given simple math and the area\u2019s food chain, it\u2019s a near certainty that some of the furry allies will meet their end in the tightening coils of an invasive python. However, instead of literally feeding the ongoing problem, their demise will help conservationists continue their work restoring a semblance of balance to the native ecosystem.<\/p>\n<p class=\"article-paragraph skip\">\u201cWe\u2019re not putting these animals out there and in harm\u2019s way,\u201d Crocodile Lake National Wildlife Refuge manager Jeremy Dixon <a href=\"https:\/\/cbs12.com\/news\/local\/possums-vs-pythons-how-floridas-only-marsupial-became-a-weapon-against-invasive-snakes\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">told the South Florida Sun Sentinel on April 19<\/a>. \u201cHarm\u2019s way is there.
