caption: The image shows a collection of three different types of seashells on a purple surface, along with two papers with text and a barcode. The papers appear to be from the Zoologisch Museum in Amsterdam, as indicated by the text on the papers. The shells are arranged in a neat row, with the largest one in the center and the two smaller ones on either side. The colors of the shells range from light brown to dark brown, and the text and barcode are clearly visible.
