The video shows a large alligator swimming in a body of water. The alligator is mostly submerged, with only its head and back visible above the water's surface. The water appears to be murky, with some green plants visible beneath the surface. The alligator's skin is a dark greenish-gray color, and it moves slowly and gracefully through the water. The video is taken from a close distance, allowing for a clear view of the alligator's features, including its sharp teeth and powerful jaws.
