caption: The image shows a pair of scallops on a black surface, with two papers containing text and a barcode beside them. The papers appear to be from the National Museum of Natural History, as indicated by the text on the papers. The shells are of various sizes and shapes, with some having a smooth, glossy finish and others having a more rounded shape. The barcode is located at the bottom of the papers, and the text is written in a neat, cursive font.
