What does a radula look like?

A radula is a unique feeding organ found in many mollusks, resembling a ribbon-like structure covered with rows of tiny, tooth-like projections. These teeth, made of chitin, vary in shape and size depending on the species and their diet, allowing them to scrape, cut, or pierce food. The radula moves back and forth, functioning similarly to a tongue, to aid in feeding. Its appearance can range from smooth to highly serrated, reflecting the mollusk's feeding habits.
