Slate: Are the sandworms of 'Dune' really worms?
UC snake expert sheds light on the locomotion of Frank Herbert's creepy desert monsters
Are the sandworms depicted in the science fiction blockbusters “Dune” and “Dune: Part II” really worms?
Slate spoke to a University of Cincinnati biologist to see if there are real biological analogies to the wormlike leviathans depicted in the Frank Herbert books and movies.
UC College of Arts and Sciences Professor Bruce Jayne is an expert on snakes and the fascinating ways they move, swim and climb without benefit of limbs.

Jayne said Dune's sandworms don't move like earthworms, which propel themselves forward using fluid-filled sacs that expand and contract in synchrony.
Instead, the sandworms move in a straight line like an enormous python in an undulating, rippling movement called rectilinear locomotion.
“The skeleton is basically sliding inside of the skin,” Jayne told Slate.
But this locomotion isn't known for speed.
Jayne said the sandworms of Dune are fast-moving burrowers in the sand, which is more like the movement found in a family of legless lizards. Like the fictional sandworms, some species of legless lizards burrow in sand dunes.
And like sandworms, the legless lizard can detect the vibrations of prey in the sand while hunting.
Jayne has studied snakes around the world. In 2021, he and his research colleagues discovered a form of snake movement new to science they called lasso locomotion.
