Jellyfish expert Lisa Gershwin, curator of natural science at the Queen Victoria Museum and Art Gallery in Tasmania, caught the unnamed species in early March while swimming near a Tasmanian jetty with a “phototank” — a small aquarium that makes it easier 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.
Though the glowing jelly is Gershwin’s 159th species discovery in Australia, she still finds the discovery “simply splendid.”
For one, the jelly is relatively large — 13cm long, but — the invertebrate is also incredibly fragile—it shatters as soon as it touches a net, she said.
