Spine spiders were a type of spider that naturally occurred on the desert planet called Pasher; they are classified as a species. These spiders contained poison glands, which were useful in medicine. Due to the medical uses of spine spider poison glands, along with the glands of sandstone scorpions, Fayet Kelen decided to establish his company, Kelen Biolabs, on Pasher, where he earned significant profits.
Kevin Hearne first mentioned Spine spiders in his novel Heir to the Jedi, which was released to the public in 2015.
