Xenobiology is sometimes used as a synonym for astrobiology, but there is a distinction between the technical terms.
- Astrobiology looks elsewhere for carbon-based life that uses water as a solvent, in other words, life as we know it, but in space.
- Xenobiology, on the other hand, looks for (/ is concerned with) life that is different from our own in some fundamental way.
For more information, see Alien Biochemistry.
Game and Story Use
- Aliens, Cryptids, and Monsters might all fall under this banner. In some cases, xenobiology may overlap with cryptozoology.
- See Alien Biochemistry for ideas and details on how life might be different from our own.
- In a science fiction or pulp genre game, you might combine xenobiology and cryptozoology, and give it all a touch of the Adventurer Archaeologist trope to make a really interesting character that runs around chasing after rare (and disputed) forms of life.
- A game where life exists in more than just carbon-based forms might have Astrobiology and Xenobiology as seperate skills. One covers carbon-based life, and includes not just biology and botany but also medicine. The other is a broader skill that affects non-carbon life, but probably lacks the finer medicinal abilities.
