Jellyfish in Jellyfish Lake, Palau, are now a threatened species


The Jellyfish Lake in Palau in the Pacific Ocean once used to have jellyfish in millions but their numbers have dwindled and now, only a few thousands remain - the blame lies on global warming and En-Nino effects. There are fears that this UNESCO World Heritage site may need to be reamed.
This has been reported in dailymail.co.uk dated 3 May 2016.
The Jellyfish Lake is a saltwater lake and has long been a source of wonder for tourists - they used to go for snorkeling among the millions of golden jellyfish that fill the water. Unfortunately, some tourists in recent weeks wre not able to come across a single jellyfish. As a result, at least one tour operator has put on hold its trips.
This situation is due to a severe drought, coupled with hotter temperatures caused by the El Nino weather pattern and warming of portions of the Pacific Ocean that changes weather worldwide and tends to push up global temperatures.
Scientists are hopeful that the jellyfish numbers will rebound when conditions improve. But, they are also worried that the global warming poses a long-term threat to the delicate ecosystem of Palau, a tiny western Pacific island chain.
As per data furnished by Palau's Coral Reef Research Foundation, the numbers of golden jellyfish at the lake had declined from about 8 million to 600,000 and the number continues to drop. In fact, the adult jellyfish have pretty much died out completely, while some young ones remain. The problem is severe because the jellyfish in the lake are a unique subspecies. They have developed in isolation from their lagoon ancestors.
