Techno-larva
A techno-larva was an engineered lifeform used by the Xindi. Typically, techno-larvae formed the  sources of such technologies as Xindi-Reptilian biorifles and Seekers. Such creatures were capable of reproducing, and thrived when exposed to omicron radiation. However, a sustained burst of delta radiation could kill this type of creature. If one techno-larva was removed from a Reptilian biorifle, another techno-larva quickly grew back in its place. ()
