Sea urchins have two primary body openings: the mouth and the anus. The mouth is located on the underside of their body and is surrounded by a structure called Aristotle's lantern, which they use for feeding. The anus is found on the top side, allowing for the expulsion of waste. These openings play essential roles in their feeding and digestion processes.
