Strongylocentrotus droebachiensis eats by using a special appendage called Aristotle’s Lantern to scrape or tear their food into digestible bits. This structure is made of five, calcareous, protractible teeth that are maneuvered by a complex muscular structure. The sea urchin crawls on top of its food and uses Aristotle's Lantern to tear up and masticate chunks of it. If food lands on the aboral surface or is caught by pedicellariae, then it is carried via podia to the mouth and devoured in the same manner.
