Jellyfish Lake's millions of jellies

A lake filled with millions of jellyfish? This might usually be considered a beautiful yet terrifying sight. At Jellyfish Lake in Palau in the western Pacific, visitors can witness the beauty upclose without experiencing the terror. The jellyfish here are essentially harmless to humans.

The lake, which locals call as Ongeim’l Tketau, is on Mercherchar Island on the southern end of Palau.
