The oxian is one of the most ubiquitous herd animals in the galaxy, raised by many different species and cultures for food, hides, and other purposes. Ranchers brought the creatures with them to help in the settlement of Nexus, and they have spread across the planet in a very short time. It is believed several subspecies of native oxian also inhabit the planet, but bear close similarities to their offworld kin.
Oxian reproduce twice a year, and have short childhoods. This fecundity has led to increased evolutionary diversity in the oxian population on Nexus, with differences in appearance from region to region already taking hold. Everywhere ranchers have brought oxian, some have turned feral adding to wild populations as well.
