American alligators are apex predators in their ecosystems, feeding on fish, amphibians, birds, and small mammals. They play a crucial role in maintaining the balance of wetland ecosystems. Despite being conservation success stories, American alligators face threats from habitat loss, pollution, and human-wildlife conflict. Conservation efforts, including habitat protection and management, aim to ensure the survival of these iconic reptiles.
