Olarian

"The Olarians are a seclusive and newly discovered species from Olara Prime in the . They possess a vast empire and control almost all of Unknown Space. Olarians do not have mammal-like lungs, instead they possess fish-like gills. They utilize protective masks and suits filled with water that keeps them alive."

The Olarians were tall, sentient aquatic species, native to the ocean-covered planet of Olara Prime in the Unknown Regions, best known to most Humans as the people to which the crime lord Screech belonged. Due to the remote position of their home territory in the Olarian Freehold, the Olarians have developed a bitter rivalry with the Chiss Ascendancy, also in the Unknown Regions. The Olarians remained largely an enigma to the rest of the galaxy, and contact with outsiders was limited.

Because of an absence of lungs, the Olarians were required special helmets that contained water to protect them when in oxygen-rich atmospheres. Because of this, Olarians were also prone to quick dehydration.
