The Bariosians come from the planet Barios II. They are humanoid beings who have similar characteristics to humans. They do have a cranial ridge that runs from their nose to the back of their head dividing their skull in half. This ridge is usually smooth, but a recessive gene causes slight smooth ridges. Most of the species' skin is light brown, but variations can occur that give a darker brown skin tone. Though mammalian, Bariosians have little to no hair as an adult. They are born with more hair but lose it as they reach adolescence.
