  • Coral Spawning -- Background

    Coral Spawning -- BackgroundReef-building corals reproduce in many different ways, but in order to make a completely new and genetically different offspring, all corals must go through these basic steps: gametes (sperm and egg cells) are produced, released by the parent corals, and then combine to form a planula, or "baby coral."

  • Coral Spawning -- Student Activity

    Coral Spawning -- Student ActivityNearly all the colonies on a reef spawn in a single night, with neighboring colonies spawning just a day or two before or after. Is this an advantage to the corals in some way? Is there a way we can test this pattern of reproduction statistically?
