Deepstaria enigmatica, is a jellyfish of the family Ulmaridae first described in 1967 by F.S. Russel. The bell of this jellyfish is very thin and wide (up to approx. 10 m), and resembles a translucent, undulating sheet or lava lamp as the animal moves. They are usually found in Antarctic and near-Antarctic seas but have been spotted in waters near the United Kingdom, at depths of 829 to 1830 meters.
