To earn the spice, humans must cope with sandworm attacks on their harvesting expeditions. In that phase the swam freely through the sand and sealed off all available water in the porous lower strata. Worm-riding is used as a coming-of-age ritual among the Fremen, and Paul's riding and controlling a giant sandworm cements him as a Fremen leader. "[12], William Touponce suggests that Herbert's depiction of larval sandworms (or sandtrout), which hold back water in the desert to maintain the arid conditions their sandworm vector requires to thrive, is "an analogy for a stage of consciousness [Paul's sister] Alia can feel. The worms are attracted to—and maddened by—the presence of Holtzman force fields used as personal defense shields, and as a result these force fields are of little use on Arrakis. At the desert edge of the plantings, the sand plankton is being poisoned through interaction with the new forms of life. Rhythmic activity as minimal as normal walking on the desert surface of Arrakis attracts the territorial worms, which are capable of swallowing even the largest mining equipment whole. [19] When water is flooded into the sandtrout's excretions, a pre-spice mass is formed; at this "stage of fungusoid wild growth", gases are produced which result in "a characteristic 'blow', exchanging the material from deep underground for the matter on the surface above it". Sandworms are a featured element in the 1992 real-time strategy video game Dune II: The Building of a Dynasty,[40] primarily as destroyers of the player's spice Harvesters, assault tanks, and other equipment. Some of the ancestral voices within her mind hold back dangerous forces that could destroy her. The reason: protein incompatibility. Sandworms are also responsible for much of the oxygen in the atmosphere, as they vent oxygen along with heat. In the absence of any more detail than quoted, I would assume there are many more species of "sand plankton" than just the one that grows into little makers, and some of those other species are autotrophic. [24][25] Rambaldi had previously created the titular alien for the 1982 film E.T. One question I have about the ecology and economy of Dune is what do the Fremen eat? The sand plankton are food for the giant sandworms, but also grow and burrow to become sandtrout. The Harvester on the ground has four scouting ornithopters patrolling around it watching for wormsign, the motions of sand which indicate that a worm is coming. By anyone's standards, Sandworms could grow to an enormous size. the Extra-Terrestrial. The Fremen saw the Sandworms as the physical manifestations of their One God from their original Zensunni religion. "[32], Besides film and television adaptations, the Dune franchise has been adapted into a series of computer and video games in which sandworms play a part. No Title [[|250px]] Sheeana stands before a sandworm, from the cover of Heretics of Dune' No Title No information Harvesting vehicles must be airlifted in and out of the sand sea in order to evade sandworm attacks. Poisonous water was forming there which the Arrakis life would not touch. Each one, according to Leto, carries in it a tiny pearl of his consciousness, trapped forever in an unending prescient dream.[23]. Players must also destroy a genetically engineered "Emperor Worm" to complete the game. We are to believe that the terra-forming they are doing has only existed within the last generation, with Liet Kynes' father, Pardot Keynes convincing the Fremen that they can bring green plant life to the planet in 300-500 years worth of reshaping the ecology, modified down a bit to 250 years. I've only ever read the original Dune.) [30] Daniel D. Snyder of The Atlantic was impressed by the "gargantuan" appearance of the sandworms thanks to the "staggering sense of scale" achieved by the miniature sets created by Emilio Ruiz del Río. Either sand plankton grow into sandtrout or worms burrow down to make sandtrout and the plankton are a different species - it's a little unclear.

They routinely devour melange-harvesting equipment—mistaking the mechanical rhythm for prey—but they seem to derive actual nutrition only from sand plankton and smaller sandworms, and have no actual interest in the spice. The Sand Dunes Trail traverses higher ground, passing through an area of large, open sand dunes---remnants of ancient, glacial beach ridges.The unique topography of this high and dry, desert-like habitat, inter-mingled with nearby, low, wet depressions supports many types of rare and unique plant species. These gargantuan annelids - growing as large as 450 meters in length - live extraordinarily long lives (no one knows exactly how long) and have a virtually indestructible hide. Fremen also use the sharp teeth of dead sandworms to produce the sacred knives they call crysknives. Book One in the classic conclusion to Frank Herbert's worldwide bestselling Dune Chronicles Hunters of Dune and the concluding volume, Sandworms of Dune, bring together the great story lines and beloved characters in Frank Herbert's classic Dune universe, ranging from the time of the Butlerian Jihad to the original Dune series and beyond.
