Twelve thousand years ago jellyfish were trapped in a lake, located on Eli Malk island, in the Republic of Palau.
These jellyfish have evolved uniquely and are almost completely harmless to humans. They rely on a symbiotic relationship with the algae that lives inside them to survive. They are actually farmers in their own right, diving to the lakes depths at night so the algae can feed on minerals at the bottom of the lake, only to return to the surface during the day so the algae can use the light to produce sugars that they harvest and ingest.
The lower layer of the lake is toxic to divers, with a high hydrogen sulphide content that can be absorbed through the skin, it means that snorkeling is the only safe way to enjoy this incredible natural phenomenon.
Sarosh Jacob, the photographer stated, “The experience of swimming through millions of jellyfish is quite surreal and Palau is the only place in the world where you can do just that!”
