The video shows a scuba diver standing on a platform underwater, with a large shark swimming nearby. The diver is wearing a black wetsuit and is holding onto a chain. The shark is gray and appears to be quite large, with sharp teeth visible. The water is a deep blue color, and there are small fish swimming around in the background. The shark swims around the platform, coming close to the diver at times, but never makes contact. The video captures the tension and excitement of being in close proximity to such a powerful creature.
