Biological component of a Reptilian rifle
The Xindi-Reptilian biorifle weapon is an example of biotechnology, a rifle-type energy weapon. The power cell is an lifeform resembling an eel. Its neural pathways modulate the rifle's power output; Doctor Phlox considered it the most sophisticated example of biomechanical engineering he had ever seen. If the organism was removed from the weapon, a new one grows almost immediately to replace it, therefore making it very difficult to disarm such a weapon. The organism could be killed with a sustained burst of delta radiation. Omicron radiation, however, caused the organism to thrive. (ENT: "The Shipment")
