Sord's species were a reptilian race. The species had dark green, scaly skin with a large fin, or crest, running back from the front of their heads at the mid-line of the skull. They possessed tails and clawed feet and were physically strong.
In the Star Trek: Stargazer novel series, this species is given the name of "Gnalish" and a member of the species, Phigus Simenon, is the chief engineer of the USS Stargazer under Captain Jean-Luc Picard. The Gnalish species also contains a number of sub-species including the "Fejjimeara" and the "Mazzereht."
