The Science behind DUNE

Dune. I spent a week buried in Frank Herbert's novel that took the world by (sand)storm. Immediately watched Dune part 1 (which I honestly would not of liked if I never read the book). Then on Tuesday finally saw Dune part 2 at AMC.

DUNEEEEEEEEEEEEEE.

To put it simply, I LOVE Dune. Frank Herbert's ecological imagery had my inner Earth Science/Biology nerd grasping onto every word. But something really, and I mean REALLY bothered me. And that is the fact that water kills. More specifically, Herbert writes that the Fremen (the native people of Arrakis the Desert planet) have long recognized that water is poisonous to Shai-Hulud, the sandworm. But water is life. Life IS water. All organisms need water I double, triple checked, Frank why?!!

Bri is shown banging on a "Secrets of Dune" door and there is the text "Let Me in" above her. Then theres a photo of Alix squinting with the text "Bri, Chill, its Science Fiction with Fiction in red and underline.
An old man in black and white laughs. Evil eyebrows and a background of flames have been added to the photo. MUAH HA HA HA is text written over photo.

Author Frank Herbert obviously is out there to torture me with all that is left unknown. If you're Alix then you may emphasize fiction in science fiction. But something felt off to me. Frank did too much research into Desert ecology and there's too much accuracy for me just to push the world of Dune aside as only fiction. I had to know the science and thus the secrets of Dune.

And so I started digging, looking closer, and researching. And the thing is, sandworm life DOES rely on water. In fact it stems from it. After careful analyzation I think I finally cracked it. May I present to you, the sandworm life cycle- that is indoubtedly reliant on the one thing all life is reliant on...water.

Shai-Halud Life Cycle: The mighty Sandworm begins life as microscopic Sand plankton. Sand plankton eat melange and burry themselves to grow into sandtrout. Sandtrout "wall off" water and excrete "sweet green syrup". When water mixes with the excretions the mixture ferments into pre-spice mass. The fermentation causes a build-up of gasses like CO2 resulting in a "spice-blow". Spice-blows brings pre-spice mass to the surface exposing it to sun and air which weathers it into melange or spice. The spice-blow also kills majority of the sandtrout, Surviving sandtrout enter a semi-dormant cyst-hibernation. After 6 months they metamorphasize emerging from their cysts as pre-mature sandworms about 9 meters long known as "little makers". Most little makers perish from being eaten by makers or running into sand trout's patches of water. The little makers that do make it grow into the deified maker, Shai-Hulud, growing up to 400 meters. Shai-Hulud primarily feasts on sand-plankton and is accredited for the deserts movement dispersing melange as it travels thus providing feed for sand plankton and starting the cycle over.

Therefore, sandworms, no matter how 'god-like', they may seem, still require water just like any other organism. In fact I'd argue what makes the Maker so God-like in the first place is its manipulation of water, not lack of it. In Children of Dune it's revealed that the sandtrout (thus sandworm) are an invasive species:

"The sandtrout was introduced here from some other place. This was a wet planet then. They proliferated beyond the capability of existing ecosystems to deal with them. Sandtrouts encysted the available free water, made this a desert planet and they did it to survive. In a planet sufficiently dry, they could move to their sandworm phase."
Leto II Atreides
Children of Dune

It is a well-established fact that Arrakis used to be a planet with water. This is evident through the presence of salt pans as confirmed by Imperial Planetologist Pardot Kynes. Therefore, it was the introduction of sandtrout that essentially transformed the complete ecology of an entire planet!

Dune is definitely an extreme example of the power of invasive species. But an important one none the less. Invasive species are most commonly a human derived issue and can be prevented. Below you can find some of the top research organizations on invasive species. Each site has a wealth of information and their own resources on how you can help ensure the health of our earth's diverse ecosystems.

    Great post. I argue that water may not be poisonous but can be dangerous in excessive amounts. Exhibit A
    (Couldn’t insert photo…bummer) but a certain female adult landed herself in the hospital for consuming to much water! 🤦🏻‍♀️
