The Pincushion Urchin (Lytechinus sp.) is a small Urchin that can be found among the Atlantic Ocean. Their colors can range from a beige/off-white to a green or purple. They reach a maximum size of 3-4 inches and feed on a variety of detritus, as well as algae. They are typically stationary during the day, but will come out around twilight to scavenge for food. Aristotle once wrote of the five parts of the Urchin's mouth:  "In reality the mouth-apparatus of the urchin is continuous from one end to the other, but to outward appearance it is not so, but looks like a horn lantern with the panes of horn left out."  This holds true today, as the mouth of the urchin is referred to as "Aristotle's Lantern".  The mouth of the Urchin is used to scrape algae from rockwork.  The spines of the urchin are a defense mechanism that are barbed like that of a fish hook and can inflict serious pain to the predator.  These spines can either come to a sharp point or can be stubby and blunt. Some fish will lay eggs among urchins, relying on the spines to keep them safe from predators.

He’s been working very hard to keep my tank pristine. He even has a few shells stuck to his body.
