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.”
