Wombats' fur can vary from a sandy colour to brown, or from grey to black. Like many other herbivorous mammals, they have a large diastema between their incisors and the cheek teeth, which are relatively simple. Their incisor teeth somewhat resemble those of the placental rodents ( rats, mice, etc.), being adapted for gnawing tough vegetation. Wombats are herbivores their diets consist mostly of grasses, sedges, herbs, bark, and roots. They are not commonly seen, but leave ample evidence of their passage, treating fences as minor inconveniences to be gone through or under, and leaving distinctive cubic faeces. Although mainly crepuscular and nocturnal, wombats also venture out to feed on cool or overcast days. The advantage of a backwards-facing pouch is that when digging, the wombat does not gather soil in its pouch over its young. One distinctive adaptation of wombats is their backwards pouch. Wombats dig extensive burrow systems with their rodent-like front teeth and powerful claws. Wombat in Narawntapu National Park, Tasmania
