Editing Xerolith (section)

== Physiology & Behavior ==
Studies are ongoing, but the following observations have been made:

2170-07: Colonists observe Xerolith consuming minerals at Callysto Crater. Humans learn that their diet is mineral-based.

2171-07: The habitat's external sensors pick up on what may be Xerolith calls or communication. The sample size is small, so very little can be gleaned from the readings, but the colonists have learned that they communicate in long-ranges through vibrations.

2171-08: From a non-invasive scan on a number of deceased Xerolith, it was determined that their exo-skeleton is made of perlite, iron, copper, and other trace minerals as yet to be identified. There seems to be an ability to self-repair this external shell.
