Brain spiders were predatory arachnids native to Tatooine. These creatures were known for their ability to burrow into the skull of a mammal and feed on the brain tissue for sustenance. Local rumor spread that brain spiders could acquire the knowledge and intellect of the creature they attacked, be it Human or otherwise; this was eventually disproved by scientists. Brain spiders were first mentioned in Coruscant Nights I: Jedi Twilight.
