Alligator Attack

Unprovoked alligator attacks occasionally happen. However, most are preventable, and the fatality rate is low, with around four percent of alligator attacks on humans in the U.S. have resulted in death, which mostly happened in Florida, according to a Crocdoc Fact Sheet.

Some of the attacks can be attributed to territorial alligators or nest defense. It was also reported that the risk of a fatal alligator attack is low compared to other relative risks of preventable injury-related fatality in Florida.

Several factors could be attributed to an increase in the number of adverse alligator encounters in Florida. These factors include populations of American alligators are increasing. 

In addition, more people move to the coastal and freshwater environments of Florida, which also increases the interactions between humans and alligators.

Alligators are generally less than four feet in length and are not large enough to be dangerous unless handled. However, if you encounter any alligator that might pose a threat, the public is advised to call the Nuisance Alligator Hotline at 866-FWCGATOR (866-392-4286).

Authorities said the public should also not swim outside posted swimming waters or in waters that might be inhabited by large alligators.

It is also not advisable to swim at night as alligators are most active between dusk and dawn. Pets should also not swim near water that may contain alligators, as dogs often attract an alligator's interest.
