Mutualistic Relationship: Jellyfish and Algae

Jellyfish are often characterized by drifting to and fro in the ocean currents, but millions of golden jellyfish in Palau’s Jellyfish lake break from such tradition. These jellyfish spend much of their lives on the move, for a crucial reason. Inside these golden jellies lies an algae called zooxanthellae, which provides their hosts with energy as a byproduct of their photosynthesis. The jellyfish undergo a daily migration across the lake following that of the sun in order to provide the energy the algae needs. To make sure the algae has the best care the jellyfish will even rotate counterclockwise, ensuring the algae has even exposure to the sun. This daily migration also benefits that of the lake, mixing its waters and nutrients as well as upturning small organisms at the base of the food chain. Because of the lakes isolation and lack of predators the jellyfish have lost their ability to sting. Now this lake has become a tourist’s attraction letting people swim with the gelatinous hordes and their algae counterparts.
