This is our entry in Lens-Artists Photo Challenge #47: Five Elements.
The jellyfish are one of our favorite exhibits at the North Carolina Aquarium at Pine Knoll Shores. They glow in the ultraviolet light of their display tank. At about 95% water, they literally embody the element water for the photo challenge.
These photos were taken on May 26, 2019, with an Olympus TG-5.
