The video shows a series of X-ray images of a fish. The fish is shown from different angles, and the bones are clearly visible. The X-ray images are in black and white, and the fish appears to be a small, elongated species with a long body and fins. The bones are arranged in a linear fashion along the length of the fish's body, and the spine is particularly prominent. The fish's head, tail, and gills are also visible in the X-ray images.
