Deepstaria enigmatica, is a species of 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. 60 cm), 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.
