Nile crocodiles found in Everglades.

Nile crocodiles slither into South Florida - Orlando Sentinel

If the link doesn't work I'm sorry. I did this on mobile (my pandafan account is saved on my phone which is why how I'm using it.)

interesting article, if rather alarmist. There's a news video on there as well but it just repeats a little bit of what is in the article accompanied by stock footage of crocodiles.

Step aside, Burmese python — you may no longer be Florida's scariest invasive species.

Researchers have confirmed that three Nile crocodiles were captured near Miami, and they say it's possible more of the man-eating reptiles are still out there, although no one can say for sure.

The big question now: How did they get to Florida?

"They didn't swim from Africa," University of Florida herpetologist Kenneth Krysko said. "But we really don't know how they got into the wild."

Krysko and his co-authors just published a paper showing that DNA testing proved the three animals captured in 2009, 2011 and 2014 are Nile crocs, a species whose males grow to over 16 feet long and weigh upward of 1,600 pounds.

Nile crocs are believed to be responsible for up to 200 fatalities annually in their native sub-Saharan Africa. Compare that with an annual average of six reported shark attack deaths globally.

Krysko, who works at UF's Florida Museum of Natural History, said the captured crocodiles matched genetically, meaning they are related to one another, but didn't match Nile crocs kept at Disney's Animal Kingdom and other licensed Florida attractions.

That means they probably were brought to Florida illegally by an unlicensed reptile collector who either didn't contain them properly, allowing them to escape, or, more sinisterly, planted them in the Everglades in hopes they would multiply.

The Nile croc, if it became established in the Everglades, would pose another invasive threat to its teetering ecosystem. Through crossbreeding, they could endanger the smaller, less aggressive American crocodiles, which have never been responsible for a confirmed human death in the U.S.

About 1,000 American crocodiles live in South Florida, mostly in mangroves and estuaries. Any hybrids would degrade the genetic integrity of the endangered American variety.

Nile crocs also are known to attack livestock, which would be bad news for cattle farms that border the Everglades.

Krysko and two co-authors, independent wildlife biologist Joe Wasilewski and UF wildlife ecology professor Frank Mazzotti, think more Nile crocs lurk unfound in the Everglades, but they aren't certain.

Allyson Gantt, a spokeswoman for Everglades National Park, where one of the reptiles was found, disagrees, saying no Nile crocs still roam the park.

Some Everglades visitors might not be aware of the differences between crocodiles and alligators, complicating efforts to confirm any remaining crocs. Crocodiles have angular snouts, and their lower teeth are exposed when their mouths are closed.

Alligator snouts are rounded, with few exposed lower teeth. Nile crocs are usually bronze or brownish yellow; alligators are blackish green.

All three Nile crocodiles were captured in extreme South Florida.

The first, a hatchling, was found on a front porch and sent to a Louisiana reptile exhibit. The second, a female measuring 4 feet, was captured at a park. Wasilewski kept it, but later gave it to another licensed researcher. The third was captured twice. The first trapper didn't have the proper permit, so he released the female. The croc was recaptured two years later 18 miles away by water in Everglades National Park. It was euthanized.

Bizarre that such a rare (for private collectors) reptile could be found and really scary if they can get established there.

If they do become numerous, then they could pose a problem by outcompeting the native american crocodiles as well as the alligators that actually live in the park. American crocs rarely attack people in Flordia, but with the niles around, I have a felling more and more people will appear in the news with headlines "Man/Woman Killed by Crocodile"

just as an update, here's an article providing additional information (buried within a lot more attention-grabbing stuff): https://www.washingtonpost.com/news...crocodiles-lived-in-the-everglades-for-years/

...

Klepper said the incident that led to the university study is two years old and no wild crocs have been spotted since then. He said these animals escaped a facility — Predator World — and went rogue, so no one released baby Nile crocs into the Everglades. “We’re confident this won’t be a problem,” he said.
