In this video, we see a manatee swimming in murky green water. The manatee is dark gray in color and has a rounded body with a flat tail. It moves slowly and gracefully through the water, occasionally turning its body to show different angles. The manatee's skin appears to be covered in small barnacles or similar marine growth. The water is relatively clear, allowing us to see the manatee in detail. There are no other visible creatures or objects in the water, and the manatee is the sole focus of the video.
