The Slith were a race of primitive reptiles native to the deserts of Yavin 13, the Slith awere limbless carnivores noted for their large mouths, which were filled with spiked teeth. They moved about by "swimming" through the sand and over the rocks, but could also move laterally - a motion called side-slithering - with incredible speed. The Slith lived in a nomadic, patriarchal society, with small tribes of no more than 15 individuals moving across the desert in search of food and water. Each tribe seemed to have an alpha male, two breeding females, and a male "lieutenant", in addition to immature individuals. During the Yuuzhan Vong invasion of the galaxy, Yavin 13 was devastated by the alien invaders, and the Slith civilization was all but exterminated.
