RADULA
Radula
The radula is an anatomical structure that is used by molluscs for feeding, sometimes compared rather inaccurately to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the oesophagus. The radula is unique to the molluscs, and is found in every class of mollusc except the bivalves.The above text is a snippet from Wikipedia: Radula
