/wom"bat/, n.
any of several stocky, burrowing, herbivorous marsupials of the family Vombatidae, of Australia, about the size of a badger.
[1790-1800; < Dharuk wom-bat]

* * *

Either of two species (family Vombatidae) of nocturnal Australian marsupials that are heavily built, 28–47 in.

(70–120 cm) long, and tailless. The single newborn develops in the mother's pouch for about five months. Wombats eat grasses, tree bark, and shrub roots. They make a grassy nest at the end of a long burrow. The common wombat (Vombatus ursinus) of southeastern Australia and Tasmania, considered a pest, has coarse dark hair and short ears. The rare Queensland hairy-nosed wombat (Lasiorhinus barnardi) has fine fur and longer ears; protected by law, the population lives principally in a national park.

Common wombat (Vombatus ursinus).

 any of three large terrestrial species of Australian marsupials (marsupial). Like woodchucks (woodchuck), wombats are heavily built and virtually tailless burrowers with small eyes and short ears. Wombats, however, are larger, measuring 80 to 120 cm (31 to 47 inches) long. Chiefly nocturnal and strictly herbivorous, they eat grasses and, in the case of the common wombat (Vombatus ursinus), the inner bark of tree and shrub roots. Wombats are considered pests by farmers because they dig in cultivated fields and pastures and because their burrows may harbour rabbits.

      The common wombat has coarse dark hair and a bald, granular nose pad. It is common in woodlands of hilly country along the Dividing Range in southeastern Australia, from southeastern Queensland through New South Wales and Victoria into South Australia, and in Tasmania. In historic times dwarf forms lived on small islands in the Bass Strait, but these have become extinct because of habitat destruction by grazing cattle.

      The hairy-nosed wombats (genus Lasiorhinus) are more sociable. They make a grassy nest at the end of a large underground burrow 30 metres (100 feet) long that is shared with several other wombats. They have silky fur and pointed ears, and the nose is entirely hairy, without a bald pad. The southern hairy-nosed wombat (L. latifrons) is smaller than the common wombat; it lives in semiarid country mainly in South Australia, extending through the Nullarbor Plain into the southeast of Western Australia. The very rare Queensland, or northern, hairy-nosed wombat (L. barnardi) is larger and differs in cranial details; it is protected by law, and most of the population lives within Epping Forest National Park in central Queensland, where there are only 60 to 80 remaining. Two other populations of hairy-nosed wombats became extinct in the late 19th or early 20th century, one near St. George in southwestern Queensland and the other at Deniliquin on the Murray River in New South Wales; these closely resembled the Queensland species.

      The skull of the wombat is flattened, and its bones are extremely thick. Unlike other marsupials, wombats have continuously growing rootless teeth adapted to a hard-wearing diet. The two incisor teeth in each jaw are rodentlike; there are no canine teeth. Wombats almost invariably bear one young at a time, which develops for five months or longer in a pouch that opens rearward. They become sexually mature at two years of age in the common wombat and three in the hairy-nosed wombats.
