Palau Spawning Trips

Full moon trips

When diving at Full Moon, you will experience tens of thousands of Red Snappers rise up from the deep and aggregate to start their mating manoeuvres in a spectacle full of energy and excitement while they change their colours from red to white. Not surprisingly, these huge aggregations also attract the biggest predators in Palau such as Bull Sharks, Oceanic Blacktip Sharks, and Hammerheads. Watch how they hunt actively within the large school of spawning Red Snappers. It is something only a select few people ever get to witness and you can now be one of them!

New moon trips

During the New Moon dives, 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, Paul and Richard have pioneered ‘Blackwater’ diving in Palau.

Imagine rolling off the boat in the pitch black of night, sometimes many miles away from the shallow water of the reefs, 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.

Exclusive in-depth knowledge

During these extra special Siren trips, Paul and Richard will also deliver a number of presentations about these unique dives. These talks will cover everything from the ecology of these events to how to photograph them. You will be split into 2 teams of 8 with Richard and Paul taking only 8 of you to these spectacular events each day, thereby maximizing the experience and ensuring that we only observe, not interfere with, this spectacular behavior. Please note, however, that these dives are only for the experienced diver as there can often be very strong currents at the sites where the action is happening.

About Paul and Richard

Paul Collins, who holds a Master’s Degree in Marine Science, has spent the last 4 years studying the full and new moon cycles and their effect on the marine life, establishing where and when they occur on the reefs in Palau. Together with his photo-pro partner, Richard Barnden, they have worked with Sam's Tours Palau to set up Unique Dive Expeditions which focuses on bringing divers to the right place, at the right moment, so they too can witness these spectacular events.

Richard has published many articles on the marine life in Palau and Paul, an award winning cameraman, has worked for the BBC, CNN and many other world class production houses. You can be sure that you will be able to learn from their knowledge, not only of the marine life but also how to get that once in a lifetime shot!!

An acclaimed photographer and engaging speaker, his work has been published widely in the UK, USA, Europe and Australia, including his regular column for Sport Diver magazine. He also supports conservation initiatives such as ARKive, The Zoological Society of London and EDGE of Existence (Evolutionarily Distinct and Globally Endangered) with images and expertise. He has also travelled widely throughout the Asia Pacific region and regularly leads trips to some of the world’s top dive destinations.
