Jellyfish Lake (Palau) This isn't my cup of tea, per se, as I am very squeamish about gelatinous things brushing up against my bare body parts, but if you're into that sort of thing, Jellyfish Lake in Palau looks like an amazing spectacle. Luckily, the millions of golden jellyfish have led a life of leisure and because they haven't had to fight off any predators, they've lost their sting.
Jellyfish Lake, based on the Pacific island of Palau, was once connected to the Pacific Ocean. But when the sea level dropped, jellyfish became isolated in the algae rich lake and eventually lost their sting. (Caters New Agency)
