Jellyfish Lake, Palau
Jellyfish Lake is a body of water located on the Rock Islands of Palau, specifically Eil Malk. While there are roughly 70 lakes on the Rock Island, Eil Malk is the only one connected to the ocean through tunnels in the limestone of the rock formations surrounding them. Home to this lake are millions of golden jellyfish and they migrate horizontally across the lake daily.
