Legends call them mermaid money or coins lost from Atlantis, but the truth behind sand dollars is even more amazing. In this episode of Saltwater Stories, we uncover the hidden life of these flat, fuzzy sea urchins that shape the ocean floor. Meet the living sand dollar with its velvet spines, secret breathing petals, and five tiny teeth known as Aristotle’s lantern. Discover how they clone themselves as babies, burrow to stay safe, and work together to keep the sea floor alive. By the end, you will see why these quiet ocean engineers are worth far more than their name suggests.#MermaidMoney #SandDollar #OceanAnimals #MarineBiology #SaltwaterStories #SeaLife #OceanEducation #OceanLiteracy #BluePlanet #BeachDiscovery #UnderwaterWorld #OceanConservation #LearnTheOcean #OceanExplorers #EcoEducation
