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.

Pointing to the deaths of more than half a billion bees in Brazil over a period of just four months, beekeepers, experts and activists are raising concerns about the soaring number of new pesticides greenlighted for use by the Brazilian government since far-right President Jair Bolsonaro took office in January — and the threat that it poses to pollinators, people and the planet.

Tuna auctions are a tourist spectacle in Tokyo. Outside the city's most famous fish market, long queues of visitors hoping for a glimpse of the action begin to form at 5 a.m. The attraction is so popular that last October the Tsukiji fish market, in operation since 1935, moved out from the city center to the district of Toyosu to cope with the crowds.

Kristan Porter grew up in a fishing family in the fishing community of Cutler, Maine, where he says all roads lead to one career path: fishing. (Porter's father was the family's lone exception. He suffered from terrible seasickness, and so became a carpenter.) The 49-year-old, who has been working on boats since he was a kid and fishing on his own since 1991, says that the recent warming of Maine's cool coastal waters has yielded unprecedented lobster landings.
