The Enchanting Inhabitants of Jellyfish Lake

Jellyfish Lake known locally as Ongeim’l Tketau, is home to millions of golden and moon jellyfish, a sight that is as mesmerizing as it is unusual. What makes this lake truly extraordinary is the unique evolutionary path of its jellyfish inhabitants.

Over thousands of years, isolated from predators, these jellyfish have evolved to be virtually stingless. This allows visitors the unparalleled experience of swimming amidst these ethereal creatures without fear of being stung.

The lake spans approximately 400 meters in length and is surrounded by a dense jungle, adding to its secluded charm. It’s accessible via a short hike from the nearby lagoon, a journey that offers stunning views of Palau’s green landscapes.

A Unique Ecosystem

The saltwater lake is a remnant of the last Ice Age. During that time, the rising sea water levels filled the lake basin. When the glaciers disappeared, the jellyfish were left isolated in the lake, which led to their unique evolution. It’s estimated that the lake is approximately 12.000 years old.

The Golden Jellyfish, the lake’s most famous residents, have a symbiotic relationship with algae known as zooxanthellae. During the day, the jellyfish migrate across the lake following the sun’s path, allowing the algae in their tissues to photosynthesize and produce nutrients, some of which are transferred to the jellyfish.

Visiting Jellyfish Lake, Palau

Visitors to Jellyfish Lake must obtain a permit as part of Palau’s Rock Island Southern Lagoon permit system. This measure ensures the protection and conservation of this unique ecosystem. Jellyfish Lake’s connection to the sea via a network of fissures and cracks in the limestone bedrock allows seawater from the nearby lagoon to seep into the lake during high tide.

This influx of seawater creates a nutrient-rich, oxygenated environment, providing the perfect conditions for the jellyfish to flourish. However, beyond a depth of 50 feet, the water becomes devoid of oxygen, and the concentration of hydrogen sulfide dramatically increases, making it inhospitable for any life form. The concentration of hydrogen sulfide in the lake surpasses the safety limit for humans by eightfold. As a result, scuba diving is strictly forbidden to guarantee diver safety.

In addition, the bubbles created by scuba diving equipment can get trapped under the Jellyfish’s bell, which could potentially harm them. Snorkeling, however, is allowed and is the preferred way to witness this natural spectacle.

The best time to visit Jellyfish Lake is during the morning hours when the sun is out, and the jellyfish are near the surface.
