Sea urchins use a structure called Aristotle's lantern, which consists of a complex arrangement of teeth and muscles, to scrape food from surfaces. They primarily feed on algae and other organic matter, using their tube feet to help capture and manipulate food items. Once the food is in position, the teeth of the lantern grind it down before it is directed into the mouth. This unique feeding mechanism allows sea urchins to efficiently process their food in their underwater environment.
It has a tiny mouth at the bottom of its body.

Sea urchins have a mouth located in the middle of the body, on the bottom. They move over their food (generally algae), and injest it with a small beak like appendage made up of five hard teeth and a soft tongue. This structure is known as Aristotle's lantern.
The classification of a Sea Urchin is Echinoidea

They either spit them out of there mouth or drop a spike and it makes a new body.
A sea urchin does move, but not very frequently.
Ummm...it's the thing from which a sea urchin hatches?
