The Gorn, or Gornarian Archosaur (Homo lacertae), were a sentient reptillian humanoid species native to the planet Gornar (AKA S'sgaron) in the Beta Quadrant. The Gorn state was the Gorn Hegemony.
Gorn are born from specialized eggs that belong to the different castes of Gorn society. Among the hardest to produce eggs were those of the military branches as their biology required specific environmental factors that were very hard to find naturally. An average Gorn male weighs about 215 kilograms. Their leathery hides is naturally strong which serves as natural armor. Their physical strength is even greater then what their appearance suggests as they possess a great deal of muscle mass. Though this is impressive among the males, the female Gorns are even more fearsome as they can average around 2.5 meters high and typically are 250 kilograms. As such, the females tend to be the stronger gender among the Gorn race. Due to this, it is not uncommon to see a large number of female marines and officers within the Gorn military.
The Gorn race was actually three species who were genetically identical and lived on three separate worlds. After they achieved space travel, the three Gorn races discovered one another and learnt of their similarity whereupon it was discovered, through fossil records, that none of their planets was their races true homeworld. Seeing the similarity, the three races joined one another in a single political unit.
Gorn mythology states that the founders of their species consists of the Mistress of Fertility S'Yahazah and a figure known as the "Great Father". Emphasis would be placed on the Great Egg Bringer S'Yahazah for she saved the young Gorn eggs from being devoured by their father. The Great Father would be banished into space and never be worshiped again.
Among Gorn, there exists a scale coloration which is blue-yellowish. These Gorn are believed to be protected by the Mistress of Fertility for they are nobles and spiritually pure. Those hereditary families that have a large number of blue-yellow scaled Gorn are considered blessed with a symbol of Gorn strength.
The Gorn race are known to be somewhat xenophobic due to the initial encounters they made with other races. Gorn starships are created to reflect the attitude of the Gorn race which is straight forward and to the point. What little contact the Federation had with this reptilian race lead most to think of it as an aggressive species, dominated by warriors. Further observation both reinforced and contradicted this. Individual Gorn exhibit aggressive, assertive and determined behavior. They seem set in their ways, and it's difficult to get them to deviate from their planned courses of action. While interaction between Humans and Gorn remains limited, they now work together.
