The video shows a skeleton of a large marine animal, possibly a whale, lying on the ocean floor. The skeleton is covered in algae and coral, indicating that it has been underwater for a long time. The bones are mostly intact, with some missing pieces. The surrounding water is clear, and the ocean floor appears to be sandy with some rocks. There is no visible movement in the video, suggesting that the skeleton is stationary. The lighting is natural, with sunlight filtering through the water, casting shadows on the skeleton.
