The life cycle of a sea urchin begins with the release of eggs and sperm into the water, where fertilization occurs. The fertilized eggs develop into free-swimming larvae known as pluteus, which undergo several stages of development while drifting in the ocean. After a few weeks, the larvae settle to the seafloor and metamorphose into juvenile sea urchins. These juveniles then grow into adult sea urchins, completing the cycle.
