The sand dollar life cycle begins with fertilization, where eggs and sperm meet in the water. Larvae hatch and develop into a juvenile stage called a "sand dollar." As they mature, they grow into adult sand dollars, capable of reproducing. The adult sand dollar eventually dies, and the cycle starts again. A diagram illustrating this cycle is helpful for understanding. https://marinelivings.com/life-cycle-of-a-sand-dollar/
