Several nights following the full moon of September every year coral species in the Cayman Islands reproduce by mass coral spawning.
The coral spawning is an event where the corals reproduce. This normally occurs only once per year.
This year however, we had a split spawning in August and in September.
About 75% of all hermatypic corals (stony corals) "broadcast spawn" by releasing gametes, eggs and sperm into the water.
Synchronous spawning is typical on coral reefs.
In Cayman most types spawn on different nights.
The most impressive are the star and brain corals.
