Look on the bright side - this luminous new jellyfish species doesn't sting.
Jellyfish expert Lisa Gershwin caught the unnamed species in early March while swimming near a jetty off the Australian island of Tasmania with a "phototank" - a small aquarium that makes it easy to photograph sea life.
The jellyfish does not emit its own light, as bioluminescent creatures do.
Rather, its rainbow glow emanates from light reflecting off the creature's cilia, small hairlike projections that beat simultaneously to move the jellyfish through the water.
