Radula
Radula explained in an easy to understand way:
Imagine trying to remove the stubborn bits of peanut butter stuck inside a jar with a spoon. This task is similar to how a snail uses its radula to scrape food particles off surfaces. Just as you maneuver the spoon to reach every corner and scrape the remnants away, the radula functions as a tonguelike organ with tiny teeth, efficiently scraping and collecting food from surfaces, much like cleaning out the jar.
