The Ithenites are a species of intelligent mammalian herbivores. Ithenites had two mouths and four throats, allowing them to speak in stereo. Female Ithenites had two humps on the back of their head, while males had but one. They had glossy, usually brown flesh. They stood roughly between 1.8 to 2.3 meters (5ft 10in. to 7ft 6in.) from eyestalk to toe. Their reflexes and coordination were somewhat slower than that of average humanoids.
In addition to allowing them to speak their unique stereophonic language, the Ithenites' four throats had the ability to violently expel air, resulting in a deafening and concussive scream.
