Three 'Man-Eating' Crocodiles Found in Florida Everglades

Animals

Florida isn't a stranger to crocodiles and alligators. After all, it is the only place on Earth where both share a habitat. But when crocodiles from across the Atlantic Ocean show up, things can get weird.

There have been three confirmed Nile crocodiles caught in Florida since 2009. DNA evidence was needed to confirm their African origin because, as University of Florida professor Frank Mazzotti told NPR's Jeremy Hobson, while there are small differences between African and American crocodiles, they are very subtle.

"From a distance," Mazzotti told Hobson on Here and Now, "it would be very difficult even for an expert to tell them apart."

The New York Times reported that most of the Nile Crocodiles in the U.S. are shipped from South Africa. The three Nile crocodiles found in Florida are believed to have been introduced through the pet trade, either for personal use or to be kept at zoos.

This type of crocodile is a "non-native species," Mazzotti explained. They were introduced to the environment, but there are no signs that the crocodiles are reproducing.

"Many introductions are failures," Mazzotti said. "The animals don't establish and breed. Ninety percent or better of introductions are failures."

There is a possibility, Mazzotti said, that there are more African crocodiles in Florida. But even those possible crocodiles don't present a threat to humans, Mazzotti explained. With no established population, Nile crocodiles don't pose the same type of threat as they do in their natural habitats in Africa where they are known as "man-eating."

All of the crocodiles captured so far have been less than 4-feet long, nothing compared to the length of adult crocodiles. Males can grow to 14-feet long; females can grow to be 12-feet long.

The coronavirus is certainly scary, but despite the constant reporting on total cases and a climbing death toll, the reality is that the vast majority of people who come down with COVID-19 survive it. Just as the number of cases grows, so does another number: those who have recovered.

In mid-March, the number of patients in the U.S. who had officially recovered from the virus was close to zero. That number is now in the tens of thousands and is climbing every day. But recovering from COVID-19 is more complicated than simply feeling better. Recovery involves biology, epidemiology and a little bit of bureaucracy too.

The future for the world's oceans often looks grim. Fisheries are set to collapse by 2048, according to one study, and 8 million tons of plastic pollute the ocean every year, causing considerable damage to delicate marine ecosystems. Yet a new study in Nature offers an alternative, and more optimistic view on the ocean's future: it asserts that the entire marine environment could be substantially rebuilt by 2050, if humanity is able to step up to the challenge.

Bread has been a source of basic nutrition for centuries, the holy trinity being wheat, maize and rice. It has also been the reason for a lot of innovation in science and technology, from millstones to microbiological investigations into a family of single-cell fungi called Saccharomyces.
