I don't know exactly, but a sea urchin is an animal that look like a blob of spikes on the sea floor. Moves very slowly. Coral is made from many tiny animals called polyps, which don't move at all in their adult life. More and more polyps grow over top one another which is pretty interesting. Over time it builds up into a structure, where only polyps on the surface are living. It is made of a type of stone I think. Correct me if I'm mistaken
