We all know Muad’Dib - the hopping rodent we’d call Jerboa on Earth.
“I will tell you a thing about your new name,” Stilgar said. “The choice pleases us. Muad‘Dib is wise in the ways of the desert. Muad’Dib creates his own water. Muad‘Dib hides from the sun and travels in the cool night. Muad’Dib is fruitful and multiplies over the land. Muad‘Dib we call ’instructor-of-boys.’ That is a powerful base on which to build your life, Paul-Muad’Dib, who is Usul among us. We welcome you.”

But like a toddler at Halloween, Paul could have chosen from a menagerie of desert animals to cosplay as.

In the original Dune, Frank Herbert sets up a really subtle piece of foreshadowing that only pays off if you continue reading past the story’s end and are willing to check out the various appendices.
At the very beginning of the book, before leaving Caladan, Dr. Yueh gives Paul a filmbook on Arrakis’ ecology and makes this comment:
The planet seems to have opened its arms to certain terranic life forms. It’s not clear how. I must seek out the planetary ecologist when we arrive — a Dr. Kynes — and offer my help in the investigation.
You only need to keep this in mind for a few hundred pages. Once you get to Appendix I: The Ecology of Dune, you realize that the good Dr. Kynes wouldn’t have needed any help with that investigation.
It was his father, Pardot Kynes, who started the terraforming efforts, which Liet-Kynes continued working on - with the active support of the Fremen.
They turned then to the necessary animal life — burrowing creatures to open the soil and aerate it: kit fox, kangaroo mouse, desert hare, sand terrapin… and the predators to keep them in check: desert hawk, dwarf owl, eagle and desert owl; and insects to fill the niches these couldn’t reach: scorpion, centipede, trapdoor spider, the biting wasp and the wormfly… and the desert bat to keep watch on these.
And while the fluid stability of the ecological system is awe-inspiring, I’d like to focus on the unsung heroes: the working animals that deserve way more recognition.

The working animals of Dune
Cielago Bats

These furry little creatures are the Fremen’s primary way of communication.
Imagine a homing pigeon, but instead of tying a written note to the body, Fremen use so-called “distrans” devices to imprint a message on the bats’ nervous system.
This modifies the animal’s normal cry to carry the message imprint, which can be deciphered by another distrans device.
And while bats are my personal favorites, anything with a nervous system can carry a distrans - some sietches use birds, but throughout the books, we’ve seen messages implanted in humans as well.
Kulon Asses
If there’s one thing I sorely missed from the movie adaptations, it’s a donkey in a stillsuit.

The only place to find a description of this majestic beast of burden is, again, Appendix I of the original Dune.
Pets were almost unknown, stock animals rare. Some smugglers employed the domesticated desert ass, the kulon, but the water price was high even when the beasts were fitted with modified stillsuits.
Whether it’s the Lynch or Villeneuve version, the cuteness rating of the movies would’ve been through the roof.
Predator Fish
Yes, indeed: fish on Arrakis.
