Rakaans were large, sentient, web-spinning predators native to Rakaa IV. They were notable for their five-phase life cycle, where they changed from one sex to another. Rakaans were land-dwellers, but they were also efficient swimmers. They had segmented bodies, mottled green, or dark-brown in color, with ten limbs. The front limbs were used as arms. Their heads were mounted on long, flexible necks, and had four segmented eyes, as well as openings for breathing and for hearing. However, their brains were in their abdomens, and their mouths were located on their underbellies. Rakaans were native to Rakaa IV's warm forests and jungles, and went into hibernation in freezing temperatures.
