Kajain'sa'Nikto, or Red Nikto, were the most common subspecies of the Nikto species. The Kajain'sa'Nikto adapted to survive in the Wannschok, or "Endless Wastes", a desert region on Kintan. They had a series of forehead ridges and small facial horns surrounding their eyes and on the chin. Their noses were covered with a movable flap of skin and a semi-permeable membrane which allowed the Nikto to breathe without ingesting sand and grit. The Kajain'sa'Nikto also had a pair of breathing tubes on each side of the neck with openings covered by similar membranes. These membranes also trapped exhaled water vapor and sent it back into their system. The Kajain'sa'Nikto equivalent of smiling was a flattening of the mouth flaps.
