Pareteorsite are composed of a hard, rock-like outer shell that is extremely difficult to break. If you drop a Pareteorsite from thousands of feet above, it will remain intact. However, this tends to cause damage to the internal components of the egg, breeding what has been called "Mad Pareteorsites."
Pareteorsites are alien parasites that traveled with The Mysterious Asteroid. The Science and Research Center in Ark City have discovered that Pareteorsite eggs are actually laid in inorganic material such as rocks despite their parasitic appearance. This is likely the reason why they were in The Mysterious Asteroid that crashed in East Ark some time ago. Pareteorsite are creatures that can be found in massive swarms, especially when fallen prey is around. Although dangerous, these aliens do not mind having owners, as long as they are well fed of course.
