- "Arcona are a reptilian species from the desert world of Cona. Although their large eyes are their most distinctive feature, Arcona actually have poor eyesight, relying instead on the powerful scent organs on their tongues and an ability to perceive body heat. Due to the heavy concentrations of ammonia in their homeworld’s atmosphere, Arcona cannot survive without ammonia supplements when away from home. Highly social, Arcona live in tight-knit nests where the needs of the group always come before those of the individual. This mentality is so ingrained that many Arcona alone in the galaxy still refer to themselves as “we” rather than “I.”"

Arcona, sometimes singular Arconan, are scaleless reptile species with humanoid bodies. Hailing from the desert planet of Cona in the Teke Ro system, they have poor eyesight, despite their large eyes, and had a small organ between their eyes which, often mistaken for their nose, helped them to see.
An Arcona's lifespan was roughly the same as a Human's. The Arcona lived in a family based community, where the males took care of the young, as the females were generally reckless and thrill-seeking. They are also notorious for their easy addiction to common salt.
Cona has been a source of metals and minerals for galactic corporations for centuries, and in that time, a peculiar blight has hit the Arcona populace. The results of salt—simple sodium chloride—interacting with their optic nerves creates an addictive, hallucinatory array of colors in their vision. As a deadly side effect, the salt destroys their ammonium-utilizing pancreatic organ. Arcona salt addicts will do whatever they can to feed their addiction, while Arcona non-addicts will attack those smuggling salt to Cona. The female Arcona, which are generally less responsible than the male, form the bulk of the addict population. Addicts need 25 grams of salt per day, or they will suffer physiological pangs of withdrawal. Arcona salt addicts are easily recognized by the color of their eyes—they are a glittering gold instead of the usual green color.
Before they made contact with other beings, the Arcona were not technologically advanced. Although they eventually used sentient technology, they never developed any of their own. When scouts from the Old Republic first arrived on Cona, many Arcona were extremely enthusiastic about exploring the galaxy. Oftentimes, whole communities sought to travel off-world. As a consequence, Arconan colonies were quite common throughout the galaxy. After becoming used to other species’ technology not present on Cona, the Arconan were commonly seen in every spaceport in the galaxy
