Coral Spawning Night Dives with Silverswift!

It’s been described as “sex on the reef” and Silverswift will once again be conducting Coral Spawning Night Dives for certified divers to experience this unique natural annual phenomenon, predicted to occur (but not guaranteed) by our Reef Biosearch marine biologist experts around 22 - 24 November.

Travelling aboard our luxury dive and snorkel catamaran Silverswift to Great Adventures’ Norman Reef platform, certified divers will be able to experience two fully guided night dives while a guided snorkel tour is available for experienced snorkellers. If you are travelling with non-diving companions, the underwater observatory is a great spot to get a diver’s view!

In addition to the chance to witness coral spawning, exciting night dives present the opportunity to see a whole new cast of nocturnal reef life.

Coral Spawning was first scientifically witnessed 30 years ago by several marine biologists working on the Great Barrier Reef. It’s Mother Nature’s way of maintaining a consistently robust coral gene pool. Predicting when this will occur is not an exact science but does rely on several environmental cues. The ocean temperature needs to be 26 degrees celcius or above for the month before for the gametes to mature. Secondly, they will generally reproduce 4 to 6 nights after the full moon in November or December when there is little tidal movement. Thirdly, it will generally be about 2-3 hours after the sun sets, because it’s nice and romantic!, but more importantly most of the plankton feeders will be asleep, giving the eggs more time to settle to the relative safety of the reef.
