Video: What it's like to swim in 'Jellyfish Lake'

Jellyfish Lake, located on Eli Malk Island in the Republic of Palau, is home to vast numbers of moon and golden jellyfish, which thrive there without predators. Filmmaker Sarosh Jacob has captured the creatures on his Canon 5D camera.The two species of jellyfish became trapped in the natural basin when the ocean receded 12,000 years ago. Both species of jellyfish have gentle stinging cells (nematocytes) but these are not powerful enough to cause real harm to humans. Swimmers report light stinging sensation only on sensitive areas, such as the mouth (and presumably other, more personal, parts).
Visitors to the lake are not allowed to scuba dive because of a nutrient layer containing large quantities of stinky hydrogen sulphide that is toxic to humans. The effects of hydrogen sulphide are less severe when it enters through the skin (as it would do for divers) than if it is breathed in -- a single breath of gas containing hydrogen sulphide can cause you to enter a coma.

Says a lot about a species surviving in a lake after the ice age and the sea receded....I don’t think there is a jelly fish in Loch Ness though lol.
