Gorn are a cold-blooded, reptilian species with green, rubbery skin and an average height of approximately two meters. They tend to be many times stronger than most humanoids, albeit slower and less agile but with greater stamina and, like most cold-blooded species, prefer warmer temperatures. Some Humans underestimate the Gorn because of an opinion that all reptiles are less intelligent than mammals. This is unwise, as the Gorn are at least as intelligent as humans.
Their ears are simple holes on the sides of their skulls, while their mouths boast an impressive array of sharp teeth and their hands and feet possess vicious claws. Mirror Phlox quipped that the Gorn were comparable to that of the extinct Velociraptor, based on one Gorn's size and bite radius. Some Gorn display eyes that are silvery and faceted, much like the compound eyes of insects, while others have typical humanoid eyes complete with pupils.
