Florida's Most Frightening Sound: The Roar of Alligators

A video filmed in Florida is leaving thousands speechless, capturing the deep, guttural roars of American alligators during their mating season.

Shared on the Facebook page Matt Devitt Weather with the caption "Turn up the volume! This is what alligator mating season sounds like," the clip has garnered over 460,000 views and thousands of reactions in just a few days.

In the video recorded by user Mark M, you can hear the resonant bellow male alligators make to attract females and warn competitors to stay away from their territory.

This is no ordinary sound: it blends audible frequencies with infrasound below 20 Hz, inaudible to human ears but capable of traveling up to 500 meters and creating visible ripples in the surrounding water—a phenomenon known as the "water dance."

The footage shows two adult alligators at the edge of a body of water, with a metal fence in the background, indicating an urban or park-like setting.

This scene is increasingly common in Florida during these months.

Alligator Mating Season Peaks in May

Alligator mating season in Florida stretches from April to June, with May being the peak period of activity. During this time, male alligators defend territories spanning two to three kilometers of water, venture into urban areas in search of mates, and reach their highest levels of aggression and territorial behavior.

The roars last between 10 and 20 seconds, occurring mainly in the mornings. Although both males and females vocalize, only males produce significant infrasound, according to scientific research from 1989.

Encountering these reptiles in populated areas is a frequent occurrence in the state. A giant alligator over 11 feet long recently startled police officers in Orange County, near apartment complexes. In Sarasota County, another adult was found in front of a private residence.

Rising Human-Alligator Interactions

Florida is home to approximately 1.3 million American alligators distributed across its 67 counties, making it the second-largest population in the United States. Urban expansion has increased human encounters with these animals, especially during the breeding season.

The Florida Fish and Wildlife Conservation Commission reported 27 attacks in 2025, two of which were fatal, a 12% increase from 2024. Since 1948, around 500 attacks have been documented, with about 30 being fatal. However, a study by the University of Florida concluded that 96% of incidents result from risky human behavior, such as swimming in areas known to have these reptiles.

Safety Precautions During Mating Season

Authorities advise maintaining a minimum distance of 30 meters from any vocalizing alligator, as they are on high alert during the mating season. Swimming in waters inhabited by alligators is one of the most dangerous behaviors for residents or tourists in Florida during these months.

While the likelihood of an unprovoked severe attack is one in 3.1 million, according to the state commission, the presence of alligators near homes necessitates heightened caution over the next two months.
