Jellyfish / sea jellies
Every ocean - from surface to deep sea, some species are found in freshwater
There are more than 2,000 known types of jellies in the world. Some scientists believe that there could be more than 300,000 species still yet to be discovered.
Sea World guests will soon be taken on a journey into the illuminated world of sea jellies.
The exhibit, scheduled to open later this year, will house a variety of local Australian species.
