The video shows a large alligator swimming in a body of water. The alligator's body is mostly submerged, with only its head and back visible above the water's surface. The alligator's skin is dark green and rough, with visible scales and ridges. The water is murky and green, with small ripples and bubbles around the alligator. The alligator's eyes are open and alert, and its mouth is slightly ajar. The alligator moves slowly and gracefully through the water, using its tail to propel itself forward. The background is blurred, but it appears to be a natural environment with rocks and vegetation.
