Cardassians have a limited exoskeleton, most notably evident on their faces. It gives them damage resistance, and also makes them slightly harder to kill than other races.
An uneasy truce exists between the Cardassian Union and the Federation, which was finally reached in 2366. This truce has been violated, in principle at least, by both sides, but no war has been declared by either side since the truce.
The military training provided by Cardassians to their soldiers provides a slight increase in strength, dexterity, and health. This training also provides their military with combat reflexes and other advantages. These skills and advantages are all learned at a very early age. The training also produces a bond between Cardassians and the government, and also manages to convince them Cardassians are better than anyone else. This makes them tend to be belligerent.
Cardassia has a higher general ambient temperature than Terra, which gives Cardassians a tolerance to heat. The race has also developed night vision. They are generally uncomfortable if the ambient temperature is cooler than they are used to, or if lighting is bright, and especially both. Their sun produces less light but more heat than Terra's.
