Energy spiders or spice spiders were arachnids that inhabited the spice mines of Kessel. They lived in complete darkness inside the mine's caves spinning webs made of glitterstim, a rare kind of spice. The spiders would shoot webbing from their mouths to capture prey, impale them and then quickly suck the life energy from them. They were one of the many threats faced by the spice miners, especially those who wandered too deep into the caves where the spiders lived.
