Rainbow jellyfish


Jellyfish expert Lisa Gershwin caught the unnamed species in early March while swimming near a jetty off the Australian island of Tasmania...

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...

The invertebrate is also incredibly fragile—it shatters as soon as it touches a net, she said.
