The Republic of Palau is an island country which consists of more than 300 islands of different sizes. Palau is one of the most amazing places on Earth: its rain forests are full of unique plants and birds, and its territorial waters are inhabited by 130 threatened species of shark. But the most remarkable sight in the country is the lake, with over 2 million jellyfish in it. But don’t worry: over time they’ve completely lost their ability to sting.
