jellyfish lake

Jellyfish Lake is a well-known dive site in the Pacific island of Palau. It is completely isolated, but in the distant past it had an outlet to the ocean. The outlet was closed off and the high jellyfish population started to feed on quickly-reproducing algae.

Over millions of years, it became an advantage for the jellyfish to lose their stinging cells, or nematocysts. Today, the very high jellyfish population are stingless, and tourists can enjoy swimming with them much closer than would be possible anywhere else.
