The lake, which has been closed for two years due to the diminishing golden jellyfish population, has re-opened.According to marine officials, around 600,000 new golden jellyfish have appeared in the 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,” said a government statement issued by Palau’s Koror State announcing the lake’s reopening.Snorkeling in Jellyfish Lake, located in Palau.

Those wishing to visit the lake will need to go through a certified tour guide and sign an eco-pledge.The Pledge comes with a mandatory viewing of an in-flight video that educates all incoming visitors about their responsibility to be environmentally responsible, along with a checklist of dos and don’ts that is distributed upon arrival.More on Geek.com:Thousands Treated for Bluebottle Stings in AustraliaThis $800 Robot Suitcase Will Follow You Around in AirportsNew Carnival Cruise Ship Will Have ‘First Roller Coaster at Sea’last_img
