Aristotle's Lantern is a complex feeding structure found in sea urchins, consisting of a ring of calcareous plates and five tooth-like structures called "teeth." This unique apparatus allows sea urchins to graze on algae and other food sources on the ocean floor. It operates using a system of muscles and ligaments, enabling the teeth to move and grind food effectively. The structure is named after Aristotle, who first described it in his studies of marine life.
