Dune Technology - Axlotl Tank

Axlotl Tank

Axlotl tanks are a fictional technology in the Dune universe created by Frank Herbert. Axlotl technology is also mentioned in Herbert's novels Destination: Void and the The Jesus Incident but not elaborated upon. The name is presumably derived from the axolotl, an aquatic salamander native to Mexico known for its regenerative abilities.

A trade secret of the Tleilaxu, an axlotl tank is a "device for reproducing a living human being from the cells of a cadaver," a type of clone called a ghola. Later in the series, the axlotl tanks are engineered to be capable of also replicating 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.
