The gnawbarrel replaced its ancestor in the Darwin Tropical Rainforest. It has changed its diet to quilbil bark; its coloration has changed to match this flora. Its other new adaptation is its teeth; while the four rear protruding teeth have shrunken, the frontal incisor has hardened and enlarged so it can gnaw off pieces of bark to eat. It also will sometimes eat the bark off the trunk of the rainforest trunkplage, thus expanding its range to Darwin Tropical Woodland. Other than this, it is the same as its ancestor.
