The video shows a white eel swimming through the water. The eel is slender and has a smooth, shiny surface. It moves gracefully among the coral reefs, which are covered in various types of marine life. The reefs are colorful and vibrant, with hues of purple, green, and orange. The water is clear, allowing for a good view of the eel and the reefs. The eel's movements are slow and deliberate as it navigates through the water.
