Researchers have stumbled across an effective unexampled way of finding giant Burmese python , which are invasive to the U.S. and have been decimating Florida ’s local ecosystems .
While carrying out an unrelated report into the movements and behaviors of raccoons and possums in Key Largo , an island off the southerly Florida coast , researchers found that the GPS dog collar they attach to the small mammals could tail the invading Burmese pythons ( Python bivittatus ) after the supersized snakes accept the tagged animals whole .
An X-ray image shows a GPS-collar, which once sat around the neck of a possum, inside a dead Burmese python that swallowed the small mammal.
The team first made this serendipitous discovery in September 2022 , when a GPS collar attach to a possum gave off a deathrate signaling , which is emitted when an animal go several hour without moving when it should be participating . But after a few hours , the collar began to move again . Over the next few days , the collar emitted several other fatality rate signals between short periods of movement . The researchers realized that the only explanation for this unusual behavior was if the possum had been eaten by a python , the researchers wrote in astatement .
After tracking the taking into custody for around a month , the squad happen the python , a 12 - pes - long ( 3.7 metre ) female weighing a hefty 66 Lebanese pound ( 30 kilogram ) , which was then euthanized . A necropsy of the snake break that the GPS collar was still intact and fully functional inside the snake , even though the opossum had long been digested , the research worker wrote in the statement .

Researchers hold up the first python they caught using the new method.
In January , researchers successfully track another python , a 77 - pound ( 35 kg ) female person of unknown distance , after the girthy serpent swallowed a racoon with a GPS apprehension . And on Feb. 8 , the researchers tracked down another GPS collar in a pile of snake stern , which had only recently been passed by another great python , TheSouth Florida Sun - Sentinelreported .
In full , three of the 42 GPS collars attached to mammals by researchers have been take in by snakes , and another six have move missing . Although it ’s not potential to definitively say what go on to the drop collars , the investigator suspect that pythons have swallowed them and since moved outside of the study area .
Pesky pythons
Burmese pythons are massive serpent from Southeast Asia that invaded Florida in the early 1970s after being released as part of the exotic pet trade . The great Burmese python get hold in Florida so far was an 18 - foot - long ( 5.5 m ) giant weighing a exfoliation - tipping 215 pounds ( 98 kilogram ) that was get and killed in June 2022 .
The pythons have been extremely prejudicial to Florida ’s ecosystems because they are rapacious eater , reproduce rapidly and have no born marauder . As a resultant , wildlife official are lawfully postulate to kill the snakes if they find them in the wild ( and it is safe to do so ) .

In certain expanse , such as Everglades National Park , " there are no more mammalian to put these collars on , " because the snakes have extinguish local populations , take researcherMichael Cove , curator of mammals at the North Carolina Museum of Natural Sciences in Raleigh , tell The South Florida Sun - Sentinel .

In other areas , however , the unexampled trailing proficiency might work , especially when it comes to locating the Snake in underground tunnels .
The team want to go forward using Global Positioning System collars to track Burmese pythons and are currently planning a new projection with local agencies . " We need everything that we can get hold to withdraw as many pythons as possible , " Cove say .
