Coral Spawning

In the ocean’s biggest coordinated orgy, corals release millions of eggs and sperm simultaneously in response to environmental cues. Such cues can involve temperature change, lunar cycle, day length, and possibly chemical signalling. Mass spawning ensures maximum survival rates as there are not simply enough predators to eat all the eggs.
