A national park in Florida has captured a record 5.2m python using an innovative approach to tackling the invasive species.
In recent decades, the big snakes have become a menace in Florida.
Using male pythons with transmitters, it allows the hunters to track the male to find the breeding females.
In a first, scientists have captured a female python that was more than 17-feet-long.
In December 2017, snake hunter Jason Leon caught a 17-foot female Burmese python at Big Cypress that set a record.
"The team tracked one of the sentinel males with the transmitter and found this massive female nearby", researchers said in a statement.More news: The Only People to Benefit From The Khashoggi Murder is His Sons
Pythons pose a major threat to native wildlife in the state.
The preserve said on its Facebook page that the python was euthanized and its 73 developing eggs were destroyed.
The invasive species are numerous and lethal - they kill animals and birds by squeezing them until they pass out.
A 2012 study showed that since 1997, populations of raccoons in the Everglades had dropped 99.3 percent, opossums 98.9 percent and bobcats 87.5 percent.
State wildlife officials estimate there as many as 100,000 pythons in the swamp areas outside Miami.
Other efforts to remove pythons have proved less successful.
The Burmese python is native to Asia and came to inhabit the swampy lands of South Florida after people released pet pythons into the wild, reported CBS News.
