Go With The Flow

Mesmerizing jellies await your arrival upon entering Under the Bay. Ambient lighting sets the mood to enjoy these beautifully hypnotic invertebrates. Front and center is a 725-gallon cylinder tank displaying Moon Jellies, while a wall-mounted, 740-gallon gallon tank showcases the Pacific Sea Nettles.

There are more than 200 species of jellies worldwide. Jellies are made up of 95% water and have no heart, brains, bones, or other organs. Their bodies let off pulsations, but movement is primarily controlled by bay and ocean currents. Jelly species are being directly affected by climate change, their populations and range continue to increase as water temperatures rise. Discover more about this increase in jelly populations in this exhibit.
