The video shows a manatee swimming in the water. The manatee is a large, gray animal with a flat, paddle-shaped tail. It is swimming near the bottom of the water, which is covered in rocks and plants. The water is green and murky, making it difficult to see the manatee clearly. The manatee moves slowly and gracefully through the water, occasionally using its flippers to propel itself forward. There are no other animals or people visible in the video.
