At night, the temperature may be reduced to 70-75☏ (21-24☌). Provide a daytime temperature gradient of 80-85☏ (27-29☌). government banned the importation of snakes and eggs of four species, Burmese python, northern and southern African pythons, and yellow anacondas, in reaction to the python problem in southern Florida. Captive-bred ball pythons are much preferred over wild-caught specimens since the latter can fast for long periods and can be stubborn feeders. Ball pythons are docile snakes that coil into a tight ball with the head buried within when frightened. Popular companion snakes include the Boa constrictor ( Boa constrictor imperator), Rosy boa, and Ball python ( Python regius). Pet boas and pythons may be farm-bred, captive-born, or wild-caught imports. The larger species are often found near water and are strong swimmers. Some species are primarily ground dwellers, but most can be found in bushes and trees. Pythons are found in Africa, Australia, and Asia under conditions that range from rain forest to desert. Sand boas ( Gongylophis spp.) may be found in desert and savannah land and Rosy boas ( Lichanura spp.) live in dry, rocky habitats. Most boas live in environments that range from tropical rain forest to dry woodland and scrub forest. Most popular pet boas are New World species, however boas are also found in Africa and Asia. The Florida Fish and Wildlife Commission (FWC) has recorded more than 500 invasive or non-native species in the state, including tegu lizards from South America that eat rodents, Cuban tree frogs that prey on smaller species of amphibians and green iguanas that feast on native plants.The group of snakes called “boas” consists of over 40 species. But that figure, like the 1,000-plus snakes killed to date in civilian hunting programmes, is a drop in the ocean. Probably the most audacious effort came last year when two renowned snake catchers from India’s mountain-dwelling Irula tribe chanted their way across the Everglades for two months. Failed initiatives have included training dogs to sniff out the snakes and releasing pythons with radio transmitters to lead hunters to females carrying up to 100 eggs at a time. Wildlife officials admit they are fighting a losing battle. With how rapidly they’ve increased their population and expanded it appears they’re doing quite well.” “In an invasive population like Burmese pythons in south Florida this could result in a broader or more rapid distribution. “It can potentially lead to a better ability to adapt to environmental stressors and changes,” she said. Hunter, though, still sees this as an unwelcome development that could hamper already unsuccessful efforts to reduce or eliminate up to 150,000 pythons that have decimated native species including bobcats, foxes, rabbits and raccoons from the Florida Keys to north of Lake Okeechobee.

The researchers believe cross-breeding occurred before the pythons secured their foothold in Florida. Hunter stressed that the genetic markers – found only in the snakes’ mitochondrial DNA passed down through the maternal line – do not mean a new species of super-snake has suddenly been unleashed on the Everglades. That allows for the best of both worlds in the Everglades, it helps them to adapt to this new ecosystem potentially more rapidly.” “You bring these different traits together and sometimes the best of those traits will be selected in the offspring. “When two species come together they each have a unique set of genetic traits and characteristics they use to increase their survival and their unique habitats and environments,” said Margaret Hunter, a USGS research geneticist and the lead author of the report. Burmese pythons are more at home in the water. That species is smaller, faster and arguably more aggressive than its big cousin, and thrives on higher and drier ground. Instead, they were surprised to uncover “a tangled family tree”, the genetic signature of the Indian rock python present in at least 13 snakes.
