The Biggest Animals Kingdom and in The World | Numbat | The Numbat is a small, colorful creature between 35 and 45 cm at 14:18) long including the tail, with a finely pointed muzzle and an important role, bushy tail on the same body length. The underside is cream or light gray, while the tail is covered with long gray hair streaked with white. Most ecosystems with a generous supply of termites have a fairly large creature with a long, thin, sticky tongue for penetrating termite colonies and powerful forelimbs with heavy claws. Like other mammals that eat ants or termites, the Numbat has degenerated jaw with a maximum of 50 very small non-functional teeth, and even if you can chew, so it is rare, because of the gentle nature of his diet.

Consequently, although all people have the same dental formula generally follows the single model Like many front-eating animals, the Numbat has a coating unusually long, narrow tongue with sticky saliva produced by large submandibular glands. Numbats also have a scent gland, sternum, which can be used for marking their territory Although termites Numbat located mainly using perfume, has the greatest visual acuity of a marsupial, and, unusual for marsupials, has a high percentage of cones in the retina. Numbats previously had faced South Australia, Western Australia in Wales, north-western New South. However, the range decreased significantly after the arrival of Europeans, and the species has survived in only two small parcels of land in the woods Dryandra and Perup Nature Reserve, both in Western Australia.

Numbats are insectivores and eat an exclusive diet of termites. An adult Numbat requires up to 20,000 termites each day. The only marsupial that is fully active during the day, the Numbat spends most of his time in search of termites. You dig the loose soil of termites with its front claws and capture with its long sticky tongue. Are known predators of carpet pythons numbats, introduced red fox, and various hawks, falcons and eagles. The animal usually remains in that territory during this period male and female territories overlap, and in season, breeding males will venture outside their normal home range to find partners.

While the Numbat has claws relatively powerful for its size, is not strong enough to get the termites in their concrete-like mound, and must wait until the termites are active. It uses a well-developed sense of smell to identify shallow tunnels and underground added that termites construct between the nest and feeding sites, which are usually a short distance below the soil surface, and most vulnerable to the Numbat digging claws. The Numbat synchronises its time with the activities of termites, which depends on temperature: in winter, it feeds from mid morning to mid afternoon in summer, rises earlier, takes refuge in the warmth of the day and feed again in the afternoon.

At night, the Numbat retreats to a nest, which can be a register or a hollow tree, or in a burrow, a tree typically close to 1-2 meters long, ending in a spherical chamber lined with soft plant material: grass, leaves, flowers and shredded bark. Numbats vocalizations are relatively few, but were reported to hiss, growl, or make 'silent' a repetitive sound when disturbed. Numbats race in February and March, normally producing one litter per year, although capable of producing a second if the first is lost. It was home to a wide range of forest habitats and semi-arid. The deliberate release of the European red fox in the 19th century, however, has erased the entire Numbat population of Victoria, NSW, South Australia and the Northern Territory, and almost all numbats in Western Australia.

Being diurnal, the Numbat is much more vulnerable to predation than most other marsupials of similar size: its natural predators, Little Eagle, Brown Goshawk, Collared Sparrowhawk and Carpet Python. When the government of Western Australia has implemented an experimental program of baiting Fox Dryandra (one of two remaining sites), Numbat observations increased by a factor of 40. Intensive research and conservation program since 1980 has managed to significantly increase the population Numbat, reintroductions and Fox free zones began. Despite the encouraging degree of success so far, the Numbat remains at high risk of extinction and is classified as endangered species.
