Blue-Black Sea Urchin
The Blue-Black Sea Urchin uses its special jaw, often referred to as Aristotle's lantern, to scrape algae as well as other food off the hard reef coral and rocks. Its then swept into the mouth by its tube feet. Similar to a starfish, its mouth is on the bottom and anus on top of the creature. Once inside the mouth, it is passed to the esophagus.
