Jellyfish Lake lies on Eil Malk Island, also called Mecherchar, the major island of the world-famous Rock Islands of Palau, within Palau’s Southern Lagoon, between Koror and Peleliu. Jellyfish Lake is also known as Eil Malk Lake.
Ongoing monitoring conducted by the Coral Reef Research Foundation (CRRF) indicated that the jellyfish populations were now rebounding after the declines that were a result of the drought conditions experienced throughout Palau in 2016.
Similar conditions were experienced in 1998 which also decimated the populations of jellyfish but eventually recovered fully as conditions returned to normal. One of many marine lakes throughout the Rock Islands Southern Lagoon (RISL), the unique environments found within these ecosystems were a strong argument for the inscription of the RISL to be a World Heritage Site.
Based on the current conditions and the continued recovery of the site, it was determined that Jellyfish Lake had sufficient numbers of jellyfish to provide visitors with a quality experience and the lake is now open to visitors!
Similar to 1998, site managers are confident that the populations of jellyfish will make a full recovery and monitoring data from CRRF supports this expectation. While Jellyfish lake is open, the Palauan government will continue to integrate appropriate safeguards to ensure the protection and sustainable use of this unique site.
