neon-jellyfish

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.

whales-king-island

Nearly 200 pilot whales and a handful of bottlenose dolphins have beached at Naracoopa on the eastern side of King Island in Bass Strait.

By Monday afternoon only 54 of the 194 pilot whales were still alive, along with seven dolphins.

According to ABC News:

Chris Arthur from the Parks and Wildlife Service says he remains optimistic about their chances.

“It’s amazing, some will some die straight away, some will survive for days.”

“These are fairly robust animals, pilot whales, we experienced that in the past.

“While they’re alive there is a chance,” he said.

Mr Arthur says there is concern for whales close to shore.

“There’s quite a large number of animals still out at sea just off shore milling around.”
