Burmese pythons completely digest prey, including skeletons. Here's how
Scientists have discovered a new type of cell that helps Burmese pythons digest the skeletons of their prey, according to the Journal of Experimental Biology.
You heard correctly, after a python swallows its meal — which can be as large as a whole deer — researchers have found why no bone fragments emerged, um, from either end. It all has to do with a newly discovered bone-digesting cell in the snakes' intestines.
Where do Burmese pythons live?
Originally from Southeast Asia, the Burmese python was introduced to southern Florida either through accidental escape or intentional release of captive animals.
The Conservancy of Southwest Florida has removed more than 20 tons — 40,000 pounds — of Burmese pythons in Southwest Florida since 2013.
The team uses 40 "scout snakes" to locate reproductive pythons during the breeding season, November through April, across a 200-square-mile area of public and private land from Naples through the Western Everglades.
"Biologists target adult female pythons, attempting to suppress python reproduction. Since 2013, the team has stopped an additional 20,000 python eggs from hatching," the Conservancy of Southwest Florida said.
What do Burmese pythons eat?
Pythons can consume meals over 100% of their body mass, feeding on a diet that includes more than 85 species, including deer, bobcats, foxes, rabbits, birds, various reptiles and other native wildlife.
Special cells allow Burmese pythons to absorb skeletons of their prey
Scientists have discovered a 'previously unknown cell type' in the walls of pythons' intestines that completely dissolves skeletons, according to a study published in the Journal of Experimental Biology.
Professor Jehan-Hervé Lignot of the University of Montpellier in France is credited with the discovery, using captive juvenile pythons as his test subjects and subjecting the snakes with three different types of diet: a normal diet with entire rodents; a low-calcium diet using rodents with no bones; and a calcium-rich diet using boneless rodents and calcium carbonate supplements.
Looking at the specialized cells in the snakes' intestines revealed "Burmese pythons possess a specialised intestinal cell type involved in excreting excess dissolved calcium and phosphorus that originate from the prey and are precipitated as particles that must accumulate in the faeces."
Snakes fed boneless prey suffer from calcium deficiencies, but too much calcium isn't good, either, and absorbing the calcium from an entire skeleton could put too much calcium into the snakes' bloodstream.
'We wanted to identify how they were able to process and limit this huge absorption of calcium through the intestinal wall,' Lignot told EurekaAlert, a nonprofit news-release distribution platform operated by the American Association for the Advancement of Science.
Burmese pythons aren't alone when it comes to the specialized cells. They've also been identified in other pythons, boa constrictors and the venomous Gila monster."
Largest pythons documented in Florida
Burmese pythons, classified as one of the largest snakes in the world, are an invasive specifies in Florida and are found primarily in and around the Everglades, where the snake represents a threat to native wildlife, according to the Florida Fish and Wildlife Conservation Commission.
The Conservancy of Southwest Florida said its scientists were recognized for capturing the largest female python ever documented to date, measuring 18 feet long and weighing 215 pounds, as well as the largest male python on record at 16 feet and 140 pounds.
Pythons may not be venomous but their bite hurts
According to the Florida Museum website, small individual pythons are not generally dangerous to people or pets.
Large Burmese pythons have large, sharp teeth, and their bites can cause severe lacerations.
➤ Florida python hunter describes python bite: 'Like a mouthful of hypodermic needles'
"They are like a mouthful of hyperdermic needles," is how the python hunter Amy Siewe described a bite from a python.

"Flesh-eating" bacteria risk increasing as ocean temperatures rise
Lifelong boat captain George Billiris says he's lucky to be alive after Vibrio vulnificus, the so-called "flesh-eating" bacteria that lurks in warm coastal waters like those along Florida's Gulf Coast, nearly killed him. "I started to get chills, feverish, my leg was swelling, burning," the third-generation sponge fisherman told CBS News. Billiris was wading in the water while fishing with his grandson back in July 2019 when he contracted the bacteria, which got into his system through a cut he had on his back leg. It was "just a little tiny scab," Billiris said. At the hospital, doctors used a marker on his leg to track the spread of the bacteria. After three weeks of treatment, the infection subsided, saving his leg from amputation. According to the Centers for Disease Control and Prevention, one in five people who contract the bacteria die after rapid spread of the infection. During hurricane season, the danger of contracting Vibrio vulnificus heightens, according to Dr. Valerie Harwood, a microbiologist at the University of South Florida. Research also shows the ocean's water temperature is rising due to climate change, which leads to more frequent and severe storms. Harwood said that because the bacteria thrives in warmer waters, it means more infections are seen in places that haven't experienced them before as water temperatures rise in those regions. "With warming waters, we are seeing cases further north," Harwood said. In recent years, cases have been reported in the Carolinas, and even as far north as Connecticut and New York. This year, there have been 17 cases in Louisiana, 16 in Florida and seven in North Carolina. Florida has reported five deaths so far, the most of any state. The bacteria can also spread through uncooked seafood, mainly oysters. These days, Billiris says he is more cautious in the water, but he still sails his family's boat nearly every day. He hopes others will recognize the symptoms of an infection, because earlier treatment could mean the difference between life and death. "Lot of people waited because they didn't know," he said.

ULA Vulcan rocket launch in Florida: Visibility map shows far beyond Cape Canaveral
Godspeed, Vulcan! United Launch Alliance will launch its third Vulcan rocket into space carrying two U.S. national security satellites − and it's possible people can see the massive rocket far outside of Florida. When ULA launches its Vulcan rocket, depending on cloud cover, Floridians (and visitors) as far as Jacksonville, Cape Coral and Miami could see it light up the sky after liftoff from Cape Canaveral Space Force Station. Visibility from most of Florida is possible, according to ULA. What's on board ULA Atlas V? Equipped with four solid rocket boosters, ULA's third Vulcan rocket will launch two U.S. national security satellites into geosynchronous orbit more than 22,000 miles above Earth. On Aug. 7, the space agency released a movie poster promoting the ULA Vulcan rocket launch complete with taglines, "Precision. Power. Purpose." and "national security begins at liftoff." The company released a movie trailer that day, too. The movie poster, movie trailer and mission patch, for the "ULA Vulcan USSF-106" mission feature a strong, god-like figure wielding a hammer (like Marvel's Thor), all with the same message: Coming soon, Aug. 12, 2025. A day ahead of liftoff, ULA continued with its heavy social media promotion, posting photos and video of the rocket rollout to the launch pad. Business is booming: Florida's Space Coast is one of fastest-growing economies in U.S. In Florida, we can best see this moment in person, particularly if you're anywhere on the Space Coast (Melbourne, Florida area), the Fun Coast (Daytona Beach area) or the Treasure Coast (Vero Beach, Jensen Beach and Fort Pierce). When there's a launch window in the middle of the night or very early morning, there's an opportunity for unique photos — the rocket lights up the dark sky and the contrail after makes for a great photo. The ULA Vulcan rocket launch is extra special because of the potential to see it far beyond the launch pad at Cape Canaveral, Florida. In the past, readers have submitted photos or posted on social platforms pictures of SpaceX Falcon Heavy, which is made up of three Falcon 9 rocket first stages, visible from Myrtle Beach. Other rocket launches have been spotted in New Jersey and Georgia. ULA's Vulcan rocket could be visible for most of Florida pending weather and clouds. Below is information on ULA's powerful rocket, the Vulcan, how to watch the rocket launch and suggestions on where to watch it from Florida and beyond. Rocket launches in Florida (a big list): Here's a roundup of all 2025 missions from Cape Canaveral and NASA's Kennedy Space Center When is the next rocket launch from Cape Canaveral, Florida? Tuesday, August 12: United Launch Alliance USSF-106 Mission: Equipped with four solid rocket boosters, ULA's third Vulcan rocket will launch two U.S. national security satellites into geosynchronous orbit more than 22,000 miles above Earth. Launch window: 7:59 p.m. to 8:59 p.m. ET Tuesday, Aug. 12, 2025 Trajectory: Due east Launch location: Launch Complex 41 at Cape Canaveral Space Force Station in Cape Canaveral, Florida Sonic booms: No Live coverage starts two hours before liftoff at : You can watch live rocket launch coverage from USA TODAY Network's Space Team, which consists of FLORIDA TODAY space reporters Rick Neale and Brooke Edwards and visuals journalists Craig Bailey, Malcolm Denemark and Tim Shortt.

You can download the free FLORIDA TODAY app, which is available in the App Store or Google Play, or type into your browser. ULA Vulcan rocket launch photos in Florida: How big is Vulcan? Where in Florida can I watch ULA Vulcan liftoff, rocket launch in person? In Florida, we can best see this moment in person if you're anywhere on the Space Coast (Brevard County) or certain spots in the First Coast or Fun Coast (Volusia County) or the Treasure Coast (Indian River County, St. Lucie County and Martin County). However, people in Jacksonville, far north of Cape Canaveral, and West Palm Beach, far south of Cape Canaveral, have posted rocket launch photos and video on X, the social platform formerly known as Twitter, and Instagram. Pro tip: If you do watch it in person, especially on Florida's Space Coast, get to your viewing destination early and prepare to stay later after the launch because of heavy traffic. A rocket launch can be a treat for the ears, too: On the Space Coast, a 'rumble' can be heard or window-shaking can be expected in some parts of Brevard County after liftoff.
