‘Risky human behavior’ is top cause of Florida alligator attacks, new study says

A University of Florida study has determined the top cause of alligator bites in Florida, and it’s probably not a surprise to anyone who’s set foot in the state.

Researchers found that “risky human behavior” is the No. 1 cause of alligator bites in Florida. In 96% of recorded incidents, “some form of human inattention or risk-taking preceded the attack,” according to the study that was released in April.

The study says the highest proportion of fatal bites happened as a result of high-risk behaviors like entering alligator-inhabited waters.

The data comes from nearly 300 years of records from 1734 to 2021 on interactions between humans and alligators using the CrocAttack.org database.

Frank Mazzotti, Ph.D., professor of wildlife ecology at UF/IFAS Fort Lauderdale Research and Education Center said the takeaway lesson from the study is that bites can be prevented.

While some recorded bites happened without apparent warning, researchers found that alligators largely do not seek conflict. Instead, they will respond when humans provide “attractive stimulus” like swimming, splashing or entering the animals’ habitats.

These actions can trigger alligators’ natural response for self-defense or to hunt.

“The most surprising finding was how high the percentage was for humans engaging in risky behavior,” the study says.

Researchers ultimately call for wildlife managers to aim for a better-educated public through improved messaging and communication about how to stay safe in gator-inhabited areas.

The findings come as alligator mating season is just kicking off in Florida. The animals’ “courtship” typically starts in April, before mating season gets into full swing from May to June, according to the Florida Fish and Wildlife Conservation Commission. It’s not uncommon to find alligators in places they don’t belong, looking for mates, during this time.

The FWC says people concerned about an alligator can call their Nuisance Alligator Hotline at 866-FWC-Gator (866-392-4286). A gator is generally considered a nuisance if it is at least 4 feet in length; if it is believed to pose a threat to people, pets or property; or if it is found somewhere it should not be, such as a swimming pool, home, garage, etc.
