Sandworm (Dune)
colossal worm-like creatures in "Dune" novels by Frank Herbert
A sandworm is a fictional extraterrestrial creature that appears in the Dune novels written by Frank Herbert, first introduced in Dune (1965).
Sandworms are colossal, worm-like creatures that live on the desert planet Arrakis. Their larvae produce a drug called melange (known colloquially as "the spice"), the most essential and valuable commodity in the universe because it makes safe and accurate interstellar travel possible. Melange deposits are found in the sand seas of Arrakis, where the sandworms live and hunt, and harvesting the spice from the sand is a dangerous activity because sandworms are aggressive and territorial. Harvesting vehicles must be airlifted in and out of the sand sea in order to evade sandworm attacks. The struggle over the production and supply of melange is a central theme of the Dune saga. The sandworms are reverently called Shai-Hulud by the planet's indigenous Fremen, who worship them as agents of God whose actions are a form of divine intervention. The name is derived from the Arabic شيء خلود (šayʾ khulūd, "thing of immortality").
Conception
The sandworms in Dune were inspired by the dragons of European mythology that guard some sort of treasure. In particular, Herbert referred to the dragon in Beowulf that guards a hoard of gold in a cave, and the dragon of Colchis that guards the Golden Fleece from Jason.
