Jellyfish Lake, Palau

If you’re lucky enough to see this view through the lens of your diving mask, you must be snorkelling in Jellyfish Lake on the island of Eil Malk in the Pacific island nation of Palau. Golden jellyfish are a subspecies unique to this small lake, on this small island – they’re found nowhere else on the planet. About a million teacup-sized golden jellyfish inhabit the lake, following the sunlight that nourishes them. Symbiotic algae live inside the jellyfish and provide their hosts with energy as a byproduct of photosynthesis. The more sun the jellyfish get, the more energy they derive. So, they start the day at the east end of the lake and drift westward until dusk, following the arc of the sun.
