In the animal kingdom, mollusks is one of the nine major classifications and includes snails, slugs, clams, mussels, oysters, squid, and octopi. Many mollusks feed using a radula, which is a saw-like organ that can cut and scrape up food. In Latin, radula means "a scraper." The Korean word for radula is 치설 (齒舌), which literally means "tooth (齒) tongue (舌)." Do not confuse 치설 (齒舌) with 칫솔 (齒-), which means "toothbrush."
