In the video, a man is seen swimming underwater in a pool. He is wearing a diving mask and snorkel and is reaching out to touch a large snake that is swimming in front of him. The snake is moving slowly and appears to be calm. The man continues to swim alongside the snake, gently touching it as they move through the water. The pool water is clear and blue, and the bottom of the pool is visible. The man and the snake are the only two creatures in the pool, and there are no other objects or people visible in the video.
