The Axlotl tanks or Axolotl tanks were living organisms within the Original Dune series and Axlotl technology is also mentioned, but not elaborated upon, in Frank Herbert's novels Destination: Void and the The Jesus Incident. Axlotl tanks are the means by which the Bene Tleilax reproduce a living human being from the cells of a cadaver, a type of cloning called a ghola as well as the creation of genetically engineered assassins known as Face Dancers. Later in the series, the axlotl tanks are engineered to replicate the spice Melange, previously only available on the desert planet Arrakis where it is created naturally as part of the life cycle of giant Sandworms.
