Unths are large herbivores native to Darwin IV. They live mostly in the tundra and mountains, and liver in herds. In Expedition, Barlowe ran across a herd of 200, some of them fighting for the right to mate, even thought they only have one gender. Unths also defend themselves with two tusks that protrutde from their skull. Despite this, they are vulnerable to Darwin IV's apex predators, the Arrowtongue and Skewer. They are seemingly Darwin IV's answer to the Triceratops and rhinoceras.
