caption: The image shows a group of five different types of seashells on a black background, with the text "Cancellaria Crawfordiana Dall, 1891" at the top. The shells are arranged in a symmetrical pattern, with each one having a unique shape and texture. The colors range from light to dark, with some having a glossy finish and others having a matte finish. The text is written in a bold, white font, making it stand out against the dark background.
