In a marine lake found on one of the islands in the Pacific Island chain of Palau, Eil Malk, an overwhelming population of golden jellyfish can be found. These golden jellies, Mastigias papua etpisoni, have been cut off from their oceanic relatives for millions of years, and as a result, lost much of their sting. They have developed a symbiotic relationship with the algae that live in their tissues, giving them their distinctive golden color. In order to live on these algae, the jellyfish have to make a daily migration across the lake, following the arc of the sun.
