The plough snail (Bullia digitalis) may be the fastest snail in the world. It extends its foot underwater and uses it like a sail to catch waves which carry it to shore. Once on the sandy beach, it uses its foot to crawl in the direction of its prey at over 2.5 cm/sec. (1 in./sec.), which it tears apart with its rasping and ripping teeth. Also known as the finger plough shell.
