Iauns are semi-sentient aquatic organisms native to the planet Iauna in the M110 galaxy.
They are peaceful creatures, usually feeding on algae or small fish like organisms. Iauns are semi-sentient and commonly swim in groups. They reproduce asexually by laying eggs.
Unfortunately, ever since the Xorthons came to Iauna, they have had to migrate to the deeper levels of their planet as the Xorthons will sometimes capture them and preserve them in aquariums or even serve them at high-class restaurants in their floating cities.
