Four Nile crocodiles have been found in Florida by scientists from the University of Florida. Between 2002 and 2004, the researchers have studied populations of crocodiles in the state. Previously, using DNA analysis, they found three Nile crocs: one was a foot-long hatchling sitting on a porch in Miami. Another was found on the property of a private zoo in Homestead, and a third, also in Homestead, a 10-pound (4.5 kg) female, was captured in a public park.
Finally, more recently, in March 2012, a three-foot-long (1 meter) female was trapped in a canal in Homestead. The researchers tagged this one and released her to
How did these crocs come to the United States? According to the study that describes the animals, they are probably from South Africa: “Our molecular analyses illustrated that two of the crocodiles we collected are most closely related to Nile Crocodiles (Crocodylus niloticus) from South Africa, suggesting this region as a source population. We, thus, documented the first known introduction of C. niloticus in Florida. Two, and possibly three of the introduced crocodiles shared the same haplotype, suggesting they are likely from the same introduction pathway or source.”
The study also says that one crocodile has escaped from the facility in Hendry County, and survived in 1,012 hectares of semi-wild habitat for three to four years, confirming that this species can survive in southern Florida.
“There are no signs of the crocodiles reproducing since arriving in Florida”, the authors of the study said. “It’s also unlikely the crocodile population has so far had any impact on native wildlife in the area”.

Nile crocodile – bigger, stronger, and more aggressive than alligator
Nile crocodiles are the second-largest reptiles on Earth, after the Saltwater crocodile. They are bigger than alligators: they can easily grow to 5.5 meters/18 feet (possibly up to 6 meters – 19.68 feet). The largest (unconfirmed) Nile crocodile is a specimen named Gustave – its claimed size is 6 meters (19 feet and 8.2 inches).
The Nile crocodile is an opportunistic apex predator and a very aggressive species of crocodile that is capable of taking almost any animal within its range. They are widely regarded as more aggressive and dangerous than alligators. Their jaws are also stronger than the alligators. It is one of the most dangerous species of crocodiles: although most attacks do not get reported, the Nile crocodile is estimated to kill hundreds (possibly thousands) of people each year, which may be more than all other crocodilian species combined.
