Snivvian
an alien race native to the planet Cadomai, the Snivvians are short-statured humanoids with protruding lower jaws studded with short fangs and tusks. Their toothy maws have earned them the nickname "Snaggletooth." Their physiology is indicative of their environment, although it is somewhat unusual. The harsh, frigid conditions on Cadomai have given them thick skin instead of heavy fur. This skin is formed of special membranes that open and close pores to regulate heat loss, in response to temperature differences. Snivvians don't sweat, since their skin doesn't exude moisture. They also don't suffer from frostbite. The adaptations of the Snivvians to their enviroment makes them excellent scouts and trackers. They have evolved a high level of genetic technology, a result of their intense desire to breed out undesirable characteristics. The Snivvian biology produces two offspring at every birth. Normally, the birth results in one male and one female child. However, a flaw in their genetics - the so-called Blood Code - produces twin males once every several million births. Only 200 such births have been recorded in Snivvian history, but all have led to trouble. The flaw reveals itself in one of the male twins, and ususally causes the male to become emotionally unstable. It mutates the male throughout his lifetime, resulting in an sociopathic individual capable of destroying Snivvian civilization. Thus, the Snivvians strove to discover the possibility of twin males and what causes one male to be flawed. However, this genetic technology has given them a false sense of security, and their strength as a race led them to become enslaved by the Thalassians several centuries before the Galactic Civil War. They were rescued by the Old Republic, which helped introduce them to hyperspace travel. This continued travel through hyperspace has somehow caused genetic changes in the Snivvians, and the possibility of male twins is on the rise. As a race, they have begun to recede, desparately trying to prevent the birth of unstable male twins. Rumors of a Snivvian destroyer began to circulate just before the Yuuzhan Vong invaded the galaxy, and many Snivvians feared that this evil being had allied itself with the Yuuzhan Vong.
