Nearly all large, reef building species release millions of gametes once a year, in precisely synchronized mass-spawning rituals. These spectacular displays allow the stationary animals to mix genetically and to disperse offspring over great distances. Such a copious delivery system is also believed to maximize the chances of fertilization, and at the same time overwhelm predators with more food than they can possibly consume. The exact cues triggering the annual phenomenon remain unclear. They are generally believed to be linked to water temperatures as well as the lunar, tidal, and twenty-four hour light cycles.
