Broadcast-spawning scleractinian corals undergo mass spawning annually, the timing of which is determined by a series of environmental and chemical cues. Most in situ observations would be expected to be approximate (Approx). Synchronous spawnings of 105 scleractinian coral species on the Great Barrier Reef. coral spawning Spawning corals rely on a hierarchy of environmental cues to coordinate the months-long gametogenesis cycles that lead up to a narrow, minutes-long mass spawning window; therefore, they are particularly sensitive to changes in the environment ( 2 ). Although captive corals currently exhibit high survival and fast growth, sexual reproduction remains a major hurdle. Reproductive strategies of the coral Turbinaria reniformis in the northern Gulf of Aqaba (Red Sea). In a new study, researchers found evidence of sound-related genes in corals, suggesting that the marine invertebrates could use sound to interact with their surroundings.
