See the amazing symbiotic relationship that has evolved between jellyfish and algae. This relationship began 12,000 years ago when ocean levels were higher as a result of melting glaciers. With the higher ocean levels, creatures like the golden jellyfish trickled into an island lake. As the ocean levels dropped, the jellyfish became trapped and evolved a symbiotic relationship with algae that require sunlight for energy and, in turn, produce sugar that feeds the jellyfish.
Because of the lack of predators, these jellyfish are now “stingless” and people from around the world travel to Jellyfish Lake in Palau to swim with these amazing animals. The experience has been described as sensual since there are millions of these jellyfish in the lake and the sensation of them rubbing against your skin is like “being wrapped in silk ribbons”.
