The image shows a group of people walking through an underwater tunnel. The tunnel appears to be made of glass and is located in an aquarium. The water is clear and blue, and there are several fish swimming around the tunnel. On the right side of the tunnel, there is a large rock formation, and on the left side, there are two people, one wearing a red jacket and the other wearing a black jacket. They are walking towards the tunnel and appear to be looking at the fish. The image is taken from a low angle, looking up at the people and the aquarium.
