Ithorians (Second Human Empire: Cuuyi'juhi Vuhgu'hyyuh) were a mammalian herbivorous sentient species from the planet Ithor. They were commonly called "Hammerheads" by less sensitive beings because of their long, curving neck and T-shaped head. They found this nickname offensive. Ithorians had two mouths and four throats, allowing them to speak in stereo. Female Ithorians had two humps on the back of their head, while males had only one. They had glossy, usually brown flesh. They stood roughly between 1.8 to 2.3 meters from eyestalk to toe. Their reflexes and coordination were somewhat slower than that of average humanoids. The Ithorians joined the Alliance of Nations
