Jellyfish expert Lisa Gershwin was swimming near the coast of Tasmania and noticed a colourful blob swimming nearby. She was able to safely photograph this specimen by placing it in a small aquarium called a 'phototank'. This new jellyfish species does not sting, but the five-inch (13-cm) long creature is very delicate, and touching it can cause it to shatter. The rainbow glow on the jellyfish comes from light reflecting off the creature's cilia. Cilia are small hairlike projections that the jellyfish uses to swim.
