The video shows a large snake with a patterned body and a long tail moving through a body of water. The snake's head is visible above the water's surface, and it appears to be swimming or gliding through the water. The snake's body is partially submerged, and it moves smoothly, suggesting that it is comfortable in the water. The water is clear, and the snake's scales are visible, reflecting the light. There are no other creatures or objects in the water around the snake.
