Alien Species

Centaurian Slugs are small non-sapient parasitic insectoids which enter a living host's body through the mouth and wrap themselves around the brain stem, releasing a toxin that produces a truth drug effect on the victim. Its appearance and lifestyle are somewhat reminiscent of Ceti Eels.

Behind the scenes[]

According to deleted material from Star Trek, these slugs are used by Klingons to interrogate prisoners in the penal asteroid of Rura Penthe.
