What's In That Lake?

Jellyfish are what's in this lake.  Jellyfish Lake (aka Ongeim'l Tketau "Fifth Lake") is a marine lake located on Eil Malk island (part of the Rock islands of Palau).  Millions of jellyfish migrate across the lake daily.   The lake is connected to the ocean by fissures and tunnels in the limestone surrounding the lake.  The most common jellyfish types in the lake are Moon Jellyfish and Golden Jellyfish.  To enjoy Jellyfish Lake one must obtain a pass ($100 for 10 days).   Scuba diving snot permitted on the lake as bubbles are damaging and after 15 meters, high concentrations of hydrogen sulfide can be absorbed through the skin leading to death.  Therefore,  snorkeling is the best option.   The jellyfish located in the lake do have stinging cells, however they aren't powerful enough to harm humans.   Some people do feel a slight sting on sensitive areas of the skin such as the mouth.   Another risk in the lake is salt water crocodiles, but attacks are rare.
