웜뱃 유대류

웜뱃 (Wombat), (가족 Vombatidae), 호주 유대류의 3 대 육상 종 중 하나. 우드 척과 마찬가지로 웜뱃은 눈이 작고 귀가 짧은 무겁게 지어진 집주인입니다. 그러나 웜뱃은 더 크며 길이는 80 ~ 120cm (31 ~ 47 인치)입니다. 주로 야행성이며 엄밀히 초식성으로 풀을 먹고, 일반적인 웜뱃 (Vombatus ursinus)의 경우 나무와 관목 뿌리의 내부 껍질입니다. 웜뱃은 경작 된 들판과 목초지를 파고 그들의 굴에 토끼가있을 수 있기 때문에 농부들에 의해 해충으로 간주됩니다.

웜뱃과 코알라 (Phascolarctos cinereus)에는 수많은 작은 형태가 있으며, 그 중 다수는 식충이며 태즈 매니아 인들과 함께

일반적인 웜뱃에는 거친 검은 머리와 대머리의 세밀한 코 패드가 있습니다. 퀸즐랜드 남동부에서 뉴 사우스 웨일즈와 빅토리아를 거쳐 사우스 오스트레일리아와 태즈 메이 니아에서 호주 남동부의 분열 구간을 따라 언덕이 많은 나라의 숲에서 흔히 발생합니다. 역사적으로 저음 형태는베이스 해협의 작은 섬에 살았지만 소를 방목하여 서식지가 파괴되어 멸종되었습니다.

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.

Contemporary wombats are related to the extinct giant wombat (Diprotodon) of Australia, which has been acknowledged as the largest marsupial in history. Some paleontologists separate giant wombats into two species (D. australis and D. minor) on the basis of differences in skull size. Other paleontologists, however, maintain that these variations can be explained by sexual dimorphism (the differences in appearance between males and females of the same species) and thus place all giant wombats in the species D. opatum. The largest giant wombats stood 1.7 metres (about 5.6 feet) tall at the shoulder and averaged 3 metres (10 feet) in length. At 2,000–2,500 kg (approximately 4,400–5,500 pounds), males weighed more than twice as much as females. Although many scientists contend that humans killed off the last giant wombats between 46,000 and 15,000 years ago, some scientists attribute its extinction to the increase in Australia’s aridity that accompanied the most recent global ice age.
