The video shows a close-up of a small octopus crawling on the sandy ocean floor. The octopus is light brown in color and has eight long tentacles that it uses to crawl. The ocean floor is covered in small rocks and shells, and the water is clear, allowing for a good view of the octopus. The octopus moves slowly and gracefully, its tentacles undulating as it crawls. The video is shot in high definition, and the colors are vibrant, with the brown of the octopus contrasting against the light blue of the water.
