Biology
Xenomorphs are usually muted black, blue, or bronze with elongated an elongated head, and varying numbers of fingers. They are carnivorous, and seem to be extremely hostile. Similar to many insects, they live under a caste society. Not much other than this is known, as there have been few encounters with them, and most have led to death of most, if not all, of those involved. Survivor accounts of them are often conflicting, and they remain very mysterious.

Culture
Xenomorphs live in a caste system in hives. Each hive is ruled by a queen. The Xenomorphs often prey on passenger ships, leading to large death tolls.
