Palau New Moon Spawning Trip

Date: 4 December 2023 to 14 December 2023


Palau Micronesia
New Moon (Bumphead Parrotfish) Spawning Special itinerary
Including Blackwater Diving
A unique experience!  A unique spectacle!

Now rescheduled to 2023 and moved to December - peak season for the very best weather conditions and expanded to a 10 night trip so you won't miss any of the action! 

We last dived Palau in 2012 and most rainbow divers will agree that it was among the top dive destinations we have ever done, perhaps the top destination in S.E. Asia. Teeming with marine life;  exhilarating drift dives; inspiring hard & soft coral encrusted walls; plus schools of sharks and other pelagic action.  Now on top of all this we add a new and even more exciting twist...

At certain times per year, during Full Moon and New Moon, you have the chance to witness a spectacular natural event: the spawning aggregations of the Bumphead Parrotfish (Bolbomeotpon Muricatum).  During this trip you will witness hundreds of Bumphead Parrotfish aggregating to start their noisy climatic mating dance! With loud bangs male Bumpheads bump their heads together like buffaloes to gain superiority over females with colour changes taking place as the fish prepare to spawn – it is not a surprise they have oversized foreheads!  From the deep, rising from the sandy bottom to the surface like a firework display, the fish release their gametes into the water column over and over again.  A truly unique spectacle!

‘Blackwater’ diving
For Night Dive lovers and those not yet convinced

For this special trip Palau Siren team up with Unique Dive Expeditions (UDE) to offer you the exceptional experience of blackwater diving.  Blackwater diving is a unique night dive which will take you miles offshore where you will hang, suspended from a 18 meter tether, over a thousand meter deep water to watch the open ocean and pelagic animals drift by.  Imagine rolling off the boat in the pitch black of night many miles away from the shallow reefs.  Here we will be able to watch one of the largest migrations on earth as all manner of weird and wonderful creatures from the depths head closer to the surface to feed. From post larval fish to Cephalopods, many smaller than your finger nail, these amazing dives present some of weirdest creatures you are ever likely to see without a submarine.

For your interest and understanding, Unique Dive Expeditions (UDE) will deliver a number of presentations about the super special Spawning and Blackwater dives. These talks will cover everything from the ecology of these events to how to best photograph them. You will be split into 2 teams of 8 with UDE taking only 8 divers to these remarkable events each day, thereby maximising the experience and ensuring that we only observe, not interfere with, this spectacular behaviour. Please note, however, that these dives are only for the experienced diver (min. 50 logged dives) as there can often be very strong currents at the sites where the action is happening.

Other Trip highlights:

German Channel
Once dived never forgotten!  The channel is over 1km long and allows for fabulous drift dives and despite the WWII damage, the coral bommies attract plenty of fish species.
Ulong Channel
Often considered the best dive in Palau! This exhilarating drift dive has it all; hard & soft coral encrusted walls, schools of sharks and other pelagic action.
Blue Corner
Steep sheer walls and an abundance of fish life. Strong currents bring plenty of blacktip, whitetip and grey reef sharks, schools of jacks and huge Napoleon wrasse.
Malakal Harbor
The harbor wall and jetty provide an excellent habitat for the smaller critters such as pipefish, spiny devilfish, juvenile batfish and a wide variety of crustaceans. 
Iro Maru Wreck
A Japanese oil supply ship sunk during World War II lies upright in just 20m of clear blue water close to the harbor of Koror.
Peleliu Island
A fast paced drift dive often different shark species can be seen along with tuna, barracuda, sweetlips and rainbow runners
Jellyfish Lake
Snorkelling Excursion or alternatives to be arranged
