In the video, a person is seen holding a mussel in their hand. The mussel is dark in color and has a shiny appearance. The person is using a small knife to carefully cut the mussel open. The background shows a container filled with other mussels, which are also dark in color. The person's hand is steady as they make the cut, and the mussel opens up to reveal the inside. The video is shot in close-up, allowing for a clear view of the mussel and the person's hand.
