The Kler'terrians were a sapient species with three flexible eyestalks evenly spaced on the crown of their heads. These eyestalks could operate independently, allowing members of the species 360-degree vision. The Kler'terrians had large mouths, with two canines protruding from the lower jaw. The species had four arms; their second set of shoulders was located directly under the first. These arms ended in hands with three fingers and an opposable thumb, and the Kler'terrians could quite comfortably manage four independent tasks with these arms. The Kler'terrian Gor'telp had a paunch.
