- Xenecology - Text by M. Alan Kazlev
Study and application (in habitat design, biospherics, etc.) of alien (non-terragen) ecologies.
- Xenobiologist - Text by M. Alan Kazlev
One who studies non-terragen lifeforms. Most survey and research vessels have at least one Xenobiologist (or equivalent turing- or superturingrade ai or expert system) on board. While some xenobiologists have a generic knowledge that is applied to xenobiota and xenecologies in general, most tend to specialize in an individual world, specific environment or world type, or even a single alien taxon or species.
- Xenobiota - Text by M. Alan Kazlev
The totality of non-terragen life on a specific planet or non-terragen ecosystem.
- Xenologist - Text by M. Alan Kazlev, based on the original by Robert J. Hall
One who studies non-terragen life-forms, especially sophont non-terragens. Xenologists are responsible for devising first contact procedures and frequently serve in the role of adviser to an alien emissary or contact intelligence. Xenology is a popular and glamorous profession, but the number of aspirants for professional xenologist outweigh by several orders of magnitude the actual vacancies available.
- Xenomorph - Text by Steve Bowers
Any Terragen entity using an artificial alien (xenosophont) body for the purposes of cultural contact, exploration or colonisation.
