|Jellyfish Lake in Palau must tbe the most famous snorkel in the world. Found on Mecherchar Island in the Rock Islands National Park, this is one of many found in Palau but the only one that has these inhabitants. The lake depths are seawater and fed by hidden channels that lead from the sea, while the top layer of water is fresh, diluted by rain.
The animals live in this unusual environment have grown and adapted to exploit their surroundings. The water in the lake is murky around the edges, which are well shaded by the hills and thick canopy of trees. benetah the roots of mangroves are occasional polka-dot cardinals hovering around, but as you swim across the lake you see one, then another, until suddenly there are hundreds of these mastigias jellies in pale apricot
The mastigias species lost their capacity to sting as their only predator is a small anemone that lives under the mangroves. They spend their days circumnavigating the lake, following the movement of the sun.
