| Definition | Water parcels in which coral gametes and larvae are aggregated during and after simultaneous spawning (often in astronomical numbers). In events that involve synchronous spawning of multiple species of corals, the concept of species-specific or group-specific biotic communities (below) may not apply, and the feature is identified at the biotic group level. |
