The video shows a long, slender eel swimming in the ocean. The eel's body is elongated and slender, with a smooth and shiny texture. It has a yellowish-green coloration that blends in with the surrounding water. The eel moves gracefully through the water, its body undulating in a serpentine fashion. The ocean floor is visible in the background, covered in rocks and coral. There are also a few small fish swimming around the eel, but they are not the focus of the video. The lighting is dim, with a blue-green hue that is typical of underwater environments.
