We call it the electronic jellyfish.

For example, the reduction in leatherback sea turtles, which feed almost exclusively on jellyfish due to longline fishing has paralleled extensive jellyfish blooms.

About 100 grams of jellyfish equals four calories.

That's how scared of the jellyfish I was.

And right in the front is the electronic jellyfish.

It's supposed to be attacking what's attacking the jellyfish.

This jellyfish, for example, has a spectacular bioluminescent display.

And here in China, Randy shot a jellyfish market.

Diana Nyad Extreme swimming with the world's most dangerous jellyfish

Made an intensified camera, wanted to make this electronic jellyfish.

And a sea that's just filled and teeming with jellyfish isn't very good for all the other creatures that live in the oceans, that is, unless you eat jellyfish.

If we're going to save the world from total jellyfish domination, then we've got to figure out what the jellyfish predators how they live their lives, like the Mola.

Here we have the extreme with dead corals, microbial soup and jellyfish.

And I knew about the jellyfish, but I was sort of cavalier.

And it does actually seem to be trying to eat the electronic jellyfish.

I've taken them to the Sea of Japan, where they met giant jellyfish.

It reaches up to almost 5,000 pounds on a diet of jellyfish, primarily.

The most venomous animal that lives in the ocean is the box jellyfish.

Now jellyfish are strangely hypnotic and beautiful, and you'll see lots of gorgeous ones at the aquarium on Friday, but they sting like hell, and jellyfish sushi and sashimi is just not going to fill you up.

But if it's a burglar alarm, you wouldn't expect it to attack the jellyfish directly.

Even in Newfoundland where we used to catch cod, we now have a jellyfish fishery.

The reason that the electronic jellyfish worked as a lure is not because giant squid eat jellyfish, but it's because this jellyfish only resorts to producing this light when it's being chewed on by a predator and its only hope for escape may be to attract the attention of a larger predator that will attack its attacker and thereby afford it an opportunity for escape.

And that predator is the giant ocean sunfish, the Mola mola, whose primary prey are jellyfish.

And then my pickled jellyfish at the Hong Kong Supermarket on Route 18 in East Brunswick.

And then another pair of legs we collaborated on were these look like jellyfish legs, also polyurethane.

These are normal mammalian cells genetically engineered with a bioluminescent gene taken out of deep sea jellyfish.

So that being said, it's highly unlikely that any jellyfish would survive that long in the wild.

Four hours into the deployment, we had programmed the electronic jellyfish to come on for the first time.

Like those big explosions, sparks, are from a little comb jelly, and there's krill and other kinds of crustaceans, and jellyfish.

And this is this voracious predator launching a sneak attack on this poor little unsuspecting jellyfish there, a by the wind sailor.

You take a glow gene out of a coral or a jellyfish and you stick it in a zebrafish, and, puff, they glow.

And when the jellyfish come and they wrap their tentacles around the fish, they're going to be busy with them, and you'll just scoot around.

So, what we end up with is a microbial zoo dominated by bacteria and jellyfish, as you see on the left in front of you.

And the only fishery left and it is a commercial fishery is the jellyfish fishery you see on the right, where there used to be prawns.

In another first occurrence in space, researchers established a gravity threshold, the point where gravity apos s effects can be observed, for two organisms Euglena and jellyfish.

And by the way, the reason the kittens here are orange and these are green is because that's a bioluminescent gene from coral, while this is from jellyfish.

And there are a lot of different animals that can do this There's jellyfish, there's squid, there's a whole lot of different crustaceans, there's even fish that can do this.

I knew there were Portuguese men o' war, all kinds of moon jellies, all kinds of things, but the box jellyfish from the southern oceans is not supposed to be in these waters.

Now, as we continue to tinker with the oceans, more and more reports are predicting that the kinds of seas that we're creating will be conducive to low energy type of animals, like jellyfish and bacteria.

So this camera platform, which we called the Medusa, could just be thrown off the back of the ship, attached to a float at the surface with over 2,000 feet of line, it would just float around passively carried by the currents, and the only light visible to the animals in the deep would be the blue light of the optical lure, which we called the electronic jellyfish, or e jelly, because it was designed to imitate the bioluminescent display of the common deep sea jellyfish Atolla.

And I was telling these kids, 120 of them they were all in the school on the gymnasium floor and I was telling them about the jellyfish and how they're gelatinous and you can't see them at night especially.

The most interesting discovery of late, I think is the so called immortal jellyfish, which has actually been observed in the lab to be able to be able to revert back to the polyp state after reaching full maturity.

Marine biologist Tierney Thys asks us to step into the water to visit the world of the i Mola mola i , or giant ocean sunfish. Basking, eating jellyfish and getting massages, this behemoth offers clues to life in the open sea.

Governments spend money on sea turtle conservation because of the role turtles play in maintaining healthy sea grass and coral reef ecosystems, reducing sponges and jellyfish, preserving the cultural and spiritual heritage of island and coastal communities, and attracting ecotourism.

Monterey Bay Aquarium Research Institute gave me time with their ROV so that I could test it and we could figure out, you know, for example, which colors of red light we had to use so that we could see the animals, but they couldn't see us get the electronic jellyfish working.
