This is either a really cool thing, or something completely terrifying – we can’t decide.
There’s a little known migration trek that takes place in Palau, a tiny collection of islands off the coast of the Philippines, that’s both beautiful and insane.
Below the waters of a landlocked lake on the southern island of Eil Malk lies a few million jellyfish that laze about in this ancient reef.
Did we mention you can swim in there?
Daily migration occurs around the lake with the jellyfish moving from one side of the lake to the other, depending on the location of the sun. Did you know these jellyfish like to get a tan too? They rotate counter-clockwise so all their little tentacles get some sun and some vitamin D to help the algae in their bodies.
Though the jellyfish do have stinging cells, they’re not powerful enough to cause harm to swimmers, so don’t worry – it’s perfectly safe.
There are two species of jellyfish that live in the lake, Moon Jellyfish and Golden Jellyfish. While snorkelling has become an increasingly popular way to view the migrating jellyfish, scuba diving isn’t allowed in the lake as the bubbles from scuba tanks can be harmful to the fish.
