Underwater passages crisscross the rock islands and may lead to underwater collapsed caverns. Through such passages, or siphons, water pumps as in a complicated circulatory system, where sea water fills caverns and spills into inland lakes, driven by pulsed celestial rhythms like a galactic heartbeat. These siphons can also lead to the mangrove roots near Jellyfish Lake, an inner island marine lake surrounded by trees. Waters here are dyed tan from leaching through the leaves. This archipelago has many such saltwater lakes created by the seepage of seawater through passages and siphons.
Jellyfish Lake is unique among the rare, only one life form dominates and it is otherworldly.
Here a small species of jellyfish has drifted in during its larval stage and flourished. The jellyfish move from the shore toward the lake's center. These small creatures form a constellation of life where invisible forces push and pull in a dance of moon, sun, tide and jellyfish. It is a unique celestial arrangement. Features of these particular jellyfish include its eyeless bell, dangling tentacles, but most importantly, the green-brown coloration in its tissue.
