American Alligator

Alligator mississippiensis

Also known as Common Alligator, Gator

American alligators act as ecosystem engineers by excavating wallows that hold water during dry seasons, providing crucial refuges for aquatic life. Dominant males produce deep, head-slapping bellows that resonate through southern swamps to establish territory and attract mates. Sows construct raised nests of decaying vegetation and fiercely guard their hatchlings for up to two years.

What to do
Never approach or corner an alligator, keep pets away, and back away slowly if it hisses.
Responsible observation
  • Keep Distance: Maintain at least 20 meters distance from water edges in alligator territory.
  • Leash Pets: Keep dogs on a short leash near freshwater bodies to avoid attracting predators.
  • Never Feed: Feeding wild alligators makes them habituated and aggressive toward humans.
