I need a new mattress.

Have you ever slept on a water bed?

Tom slept on the inflatable mattress.

Tom slept on an inflatable mattress.

And it turns out, actually, that 42 percent is the Mola mola fish.

Tom hid his money under his mattress.

I made that up because I just wanted to put up a slide of the Mola mola fish.

Do you really hide your money under the mattress?

The Mola's no exception.

So we thought, OK, this must be a spring the saddle could very well be a spring.

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

My brother hides his porn magazines under his mattress.

She was surprised to find thousands of dollars hidden in her daughter's mattress.

Molas are infamous for carrying tons of parasites.

The crud in the front is mattress stuffing, and you see that all over Turkey.

You cannot learn swimming on a foam mattress and enter into water.

And it just so happens that's a parasite hanging off the Mola.

So, the saddles that saddle shaped spring has actually been well known to biologists for a long time, not as a spring but as a visual signal.

Their other name, Mola mola, is it sounds Hawaiian, but it's actually Latin for millstone, and that's attributable to their roundish, very bizarre, cut off shape.

And over in these places, the Molas are caught in set nets that line these countries.

We were served a nine course meal of Mola after we tagged.

I set up a website because I was getting so many questions about Molas and sunfish.

Narrator With a mattress below and attached to a safety rope, Lynn began her 60 foot ascent.

And I think it's kind of a nice little cosmological convergence here that the Mola mola its common name is sunfish that its favorite food is the moon jelly.

And lots of generations, lots of tweaking and torquing, and we turn our puffer into the Mola.

If we look at the bed here, we can see that they sleep on a rug on the floor.

Rubber band a tension spring where energy is stored by stretching the material.

Usually they are given three blankets per person to be used as a pillow, blanket and a mattress respectively.

An air mattress may not be the most comfortable thing to sleep on, but it's much better than the floor.

And under those kelps this is why the Molas come there because it's spa time for the Molas there.

A spring is an elastic object used to store mechanical energy.

Two of the stones fall into the river, while the last falls into Mola Ram's hand, burning him.

And then we did a series of calculations, and what we were able to show is that these mantis shrimp have to have a spring.

And all of these are the same principles that apply to the saddle shaped spring in stomatopods.

And again, that brings us back to the importance of that spring in storing up and releasing so much energy in this system.

And the Molas there, you can find them with a spotter plane very easily, and they like to hang out under floating rafts of kelp.

The poor little Molas coming in, getting ripped to shreds, so we head down south, to San Diego.

And this is quite interesting, to find evolutionary origins of visual signals on what's really, in all species, their spring.

While Mola Ram escapes, Indy and Shorty rescue Willie and retrieve the three Sankara stones, the village children escape.

And that's actually what drew me to the Mola in the first place, was this terribly bizarre shape.

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.

But unfortunately Molas, even though they don't school, they still get caught in nets as by catch.

Indy catches the now cool stone, while Mola Ram falls into the river below, where he is devoured by crocodiles.

Suppose that the spring has reached a state of equilibrium, where its length is not changing anymore.

Imagine having to hang your mattress close to the ceiling because the sewage system often clogs and floods the room with dirty water up to 40 centimeters high.
