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, your Cruise Directors on S/Y Palau Siren offer ‘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

For your interest and understanding, your Cruise Director 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 the dive guide 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.
