  • Legend: A common resident found in kelp beds, rocky shores, and coral reefs is the sea urchin. It has a healthy appetite for organic material and feeds on kelp as pieces drift by. Sea urchins like this Purple Sea Urchin (Strongylocentrotus purpuratus) can be harmful to kelp forests and can destroy reefs when their populations multiply rapidly and overpopulate an area. They damage kelp forests by chewing through kelp holdfasts in search of food.


Attribution information, such as the author's name, e-mail, website, or signature, that was once visible in the image itself has been moved into the image metadata and/or image description page. This makes the image easier to reuse and more language-neutral, and makes the text easier to process and search for. Commons discourages placing visible author information in images.
