Make an Appointment to Spawn Together? Since the Discovery of Synchronous Spawning in 1980, This Mystery Has Puzzled the World for 40 Years. Seven Years of Fieldwork Data Show That Key Factors Are Hidden in the Monthly Cycle Since 2010, Yoko Nozawa's Research Team Has Come to Green Island for Diving Surveys Every Year During the Coral Breeding Season (Usually April, May, and June in Southern Taiwan).
During the Investigation, the Team custom t shirts Went into the Water Every Night to Record the Species, Quantity and Ovulation Time of Corals. After Accumulating 7 Years of Investigation Data, Postdoctoral Researcher Lin Zhehong Found That Each Type of Coral Has a Distinct Reproductive Pattern. According to the Existing Records of the Research Team, Corals Belonging to the Coral Family (Merulinidae) Adopt a Risk-Spreading Strategy, with Different Groups Spawning Simultaneously in Batches. Although the Spawning Days Between Groups Are Staggered, the Time Schedule Is Very Fixed, and They Are All 5 to 8 Days After the "Full Moon"; Green Island Also Has Another Large Number of Corals, Which Are Some Species Under the Genus Acropora. They Are "All" Scheduled to Lay Their Eggs on the Same Day, but the Exact Date Varies from Year to Year. "The Jomon Family Is Fixed to
Lay Eggs Five to Eight Days After the Full Moon; Axophora Is Also After the Full Moon, but There Is No Rule at All." Lin Zhehong Said. Even So, Both Spawned After the Full Moon, So the Research Team Focused on the Lunar Cycle Factor: Moonlight, to Test. 1 Image Source: Research Has Something Cordaceae Vs Axopora (Image Credit: Research Items) Repeated Indoor and Outdoor Results Show That Nighttime Light Sources Inhibit Coral Spawning Since Dipsastraea Speciosa of the
