Videos from Eil Malk island’s Jellyfish Lake in Palau can feel otherworldly. This GoPro commercial takes us underwater to swim with photographer Nana Trongratanawong and the multitudes of golden jellyfish that live in this unique wonder of nature.
These jellyfish are famous for migrating back and forth across the lake, churning “the nutrients and small organisms that form the base of the food chain” in what might otherwise be a stagnant body of water. From National Geographic:
Sunlight is plentiful on this remote Pacific island, which is a good thing because golden jellyfish don’t just enjoy basking in the sun—they need its light to survive. Solar rays nourish essential, algae-like organisms called zooxanthellae, which live symbiotically in the jellies’ tissues and provide their hosts with energy as a byproduct of their photosynthesis.
