JELLYFISH LAKE, PALAU from Sarosh Jacob on Vimeo.
Jellyfish Lake is located on Eli Malk island in the Republic of Palau. Twelve thousand years ago these jellyfish became trapped in a natural basin on the island when the ocean receded. With no predators amongst them for thousands of years, they evolved into a new species that lost most of their stinging ability as they no longer had to protect themselves. They are pretty much harmless to humans
