Jellyfish Lake is on Eil Malk island in the Republic of Palau in the Pacific Ocean. It is a marine lake, and as the name suggests it is home to a large population of jellyfish. Millions, in fact. The golden and moon jellyfish which live in the lake have been separated from the sea for so long that they have evolved into new sub-species, and perhaps even new species. They have also lost their ability to sting. The lake provides an incredible location for snorkelers and swimmers.
Below is a short film taken below the surface of the lake, showing its incredible inhabitants.
