Zoo Basel has successfully bred Fried Egg Jellyfish, a species of jellyfish found in the Mediterranean, Aegean, and Adriatic Seas. The species is particularly challenging to breed because they require live plankton to eat and plenty of sunlight to survive. These young jellies were kept behind the scenes in a special breeding tank which imitated conditions in their natural environment. They are now on exhibit at Zoo Basel's Aquarium. Unlike most jellyfish, this species is capable of propelling itself through the water and do not depend on currents to carry them.
