The k'lor'slug is a dangerous vermiform pest native to the swamps of Noe'ha'on that usually invades the darkest spots on unsanitized space vehicles. They are venomous hunters with keen olfactory and visual senses. A k'lor'slug will lay more than 300 eggs in a single birthing period, each releasing a ravenous hatchling; an infestation aboard a space vehicle will become harder to control—and more potentially fatal—the longer it was tolerated.

The k'lor'slug is one of the hologram creatures used in the game of dejarik.
