The video shows a large snake swimming through water with green plants and branches. The snake is moving slowly and appears to be exploring its surroundings. The water is clear, and the snake's scales are visible as it moves. There are also small fish swimming around the snake, but they do not seem to be bothered by its presence. The snake's head is visible, and it is looking around as it swims. The plants and branches provide a natural habitat for the snake, and the water appears to be shallow.
