It might look like someone taking their life into their own hands, but thankfully this lake is the only place in the world where you can swim safely amongst millions of jellyfish.
In ‘Jellyfish Lake’ on the Pacific island of Palau, swimmers can take a dip surrounded by thousands of the normally harmful marine animals which have all lost their sting.
The lake was once connected to the Pacific Ocean, but when the sea level dropped, the jellyfish became isolated in the algae-rich lake and have not had to defend themselves from predators.
As a result, their population has thrived, and the eight million jellyfish now in the lake have all lost their sting.
Tourists can now swim alongside the jellyfish in the 12,000-year-old lake, one of around 200 saline marine lakes now identified worldwide.
