The video shows a large snake, which appears to be a python, swimming in a body of water. The snake's body is mostly submerged, with only its head and part of its body visible above the water's surface. The snake's scales are dark and shiny, and it moves slowly and gracefully through the water. The surrounding environment is lush and green, with plants and trees visible in the background. The water is clear, and the snake's movements create gentle ripples on the surface.
