The term cremling collectively refers to many species of tiny scavenger crustaceans. They vary heavily in appearance, including different colors, tail shapes, claw sizes, and antennae lengths, though most have elongated bodies and many legs. Some cremlings are scavengers who feed on the blood and flesh of deceased creatures, while others are herbivores who feed on vegetation in the wake of a highstorm, when Rosharan flora reveal their vulnerable inner matter. Some cremling types include both in their diets. While some cremlings are venomous, most species are relatively harmless unless they gather into a sizable swarm. However, a cremling swarm—or even a single cremling by itself—may not be all it seems, as described in the Sleepless profile. Across Roshar, cremlings are considered and dismissed as irritating pests. The word is a common Rosharan insult and often used to describe cowardly behavior.
