claimCorals must release their sperm and egg packets simultaneously to successfully form new corals.
claimThe lunar-mediated spawning of corals is critical for the colonization of reefs by new generations of corals, particularly as populations face threats from mass bleaching and climate change.
claimCorals located near Eilat on the Israel-Jordan border continue to synchronize their spawning behavior with lunar cycles despite being exposed to development, pollution, and artificial light.
claimLevy and colleagues discovered that corals possess light-sensing neurons that enable them to perceive moonlight on the water.
claimOren Levy, a researcher at Bar-Ilan University, studies how light pollution interferes with the lunar-synchronized spawning behavior of corals.
accountAt a marine ecology conference, marine biologists indicated to Kristin Tessmar-Raible that lunar rhythms are a widespread phenomenon, citing coral as a famous example.
claimCorals on reefs globally, including the Great Barrier Reef and the Red Sea, time their spawning events to occur after the full moon.
claimCorals release their sperm and eggs simultaneously in a synchronous event, creating a mass release of reproductive material that floats toward the surface.

claimMarine animals such as corals synchronize their spawning to maximize the probability of an encounter between eggs and sperm, as they release eggs into the water before fertilization occurs.
claimCorals typically spawn in the evening and night within a tight time window of 10 minutes to half an hour.
claimThe northern portion of the Red Sea is considered a climate-change refuge for corals and has not experienced mass bleaching events.
quoteAnn Tarrant stated: “We know that algae like that also have circadian rhythms. So when you have a coral and an alga together, it’s complicated to know how that works.”
claimCorals and sea anemones do not possess brains.
quoteMarine ecologist Shlesinger observed coral colonies releasing bundles of eggs and sperm, noting: "You’re looking at it and it starts to flow to the surface. Then you raise your head, and you turn around, and you realize: All the colonies from the same species are doing it just now."
claimDiverse marine animals, including sea mussels, corals, polychaete worms, and certain fishes, are thought to synchronize their reproductive behavior with the lunar cycle.
claimCorals and many other species contain light-sensitive proteins called cryptochromes, which researchers have known about for at least 15 years.

claimOysters, corals, and many other ocean animals utilize 'broadcast spawning' to breed, where they release sperm and eggs simultaneously in a timed event.
accountSouth Pacific palolo worms spend most of the year feeding on the seafloor or within coral, but in the austral spring, the rear of their bodies transform into sacks of eggs or sperm.

claimThe mass spawning of corals on the Great Barrier Reef occurs between October and December, specifically triggered to happen right after a full Moon.
quote“The corals time their spawning according to several factors, including temperature, salinity and availability of food. But it always occurs between October and December and right after a full Moon.”
