Overview
An adult chull has six thick legs, large claws, antennae and a rounded, stone-like shell. When it withdraws its head and limbs, its outline can resemble a boulder. The shell incorporates minerals from food and water rather than being an ordinary mammalian hide; handlers can shape its outer surface without treating every crack as a wound in living tissue. Wild shells provide places for small organisms and plants to settle.
Domesticated chulls supply much of Roshar's slow, practical transport. Their load-bearing shells and steady hauling make them useful to traders, armies and travellers who cannot rely on expensive horses. Human care can smooth or decorate the shell, and Reshi markings can identify an animal's community. Shallan's sketchbook records multiple life stages, so the large familiar adult is not the creature's entire life cycle.
First appearances & development
The Way of Kings (2010) places chulls throughout everyday travel and military logistics. Later Stormlight novels and in-world sketches expand their biology and use. This account follows Roshar's domesticated animal rather than treating the hauling role as proof that it is an ordinary ox under another name.
Canon & continuity
The Coppermind indexes the novels and Shallan's chull sketchbook for anatomy, shell formation and life stages. Its article warns of incomplete later-book coverage. The bibliography therefore identifies specific primary witnesses without claiming a fresh full-novel reread or deriving animal statistics from the unseen RPG bestiary.

Family, evolution & connections
Hermit crabs and elephant feet
Illustrator Ben McSweeney describes the chull’s hermit-crab body and elephant-like feet as purposeful elements of Sanderson’s design brief. His July 2012 account documents illustration inputs, not Earth animals as the creature’s canonical ancestors.
