The video shows a scuba diver in a black wetsuit, wearing a black mask and breathing apparatus, swimming in the ocean. The diver is holding a camera and filming a large shark swimming nearby. The shark is grey and appears to be quite close to the diver. The water is clear and blue, and there are bubbles rising from the diver's breathing apparatus. The shark is the main focus of the video, and the diver seems to be capturing its movements on camera.
