Sea urchins do not produce pearls in the same way that oysters do. While oysters create pearls from irritants by secreting layers of nacre, sea urchins have a different defense mechanism. They can form structures called "urchin pearls," which are calcified deposits, but these are not true pearls and are generally not valued like those from mollusks. Instead, sea urchin pearls are often irregular and not sought after in jewelry.
