Jellyfish Lake is quite simply one of the most unique places on the planet! A huge lake filled to the top with aprox. 13 million non-stinging jellies (actually they do sting, but the sting is so reduced you barely notice it). A must see for every visitor to Palau. A scenic boat ride and a 10 minute walk up and over a Rock Island, takes you back into a world that existed millions of years before ours. Bring cameras, walking shoes (sandals or dive booties) and your snorkeling gear.

Once you enter the water, please be sure to move carefully and slowly, as the jellies are extremely fragile and could get harmed by fast movements. As you swim further into the lake, you will be surrounded by millions of pulsating golden globes. These are Mastigias Jellies and have evolved over millions of years into an animal that no longer needs its predatory stinging cells.

The jellies have become farmers of an algae similar to that used by coral reefs. This algae lives inside a jelly's tissues and all the algae needs to survive is sunlight where it photosynthesises the suns rays into sugars. The jelly uses an enzyme which it gets from a nitrogen rich layer of water deeper in the lake every night to capture the energy it needs from the algae. Hence, the daily cycle of following the sun in the day time and sinking deeper at night to 'fertilize' themselves.
