The Northern quoll is more than Threatened. It has a national listing of Endangered, and a Northern Territory listing of Critically Endangered.
No. In 2003 there were only 65 Northern Quolls in the Northern Territory of Australia. Scientists moved them all to two islands off Arnhem Land, where there are no cane toads. (Cane toads are poisonous but were easy prey for the quoll.) Five years later, in 2008, their numbers have increased to over 6000, according the the NT Government Scientist, John Woinarski. However, the Northern quoll is classified as "critically endangered" in the Northern Territory, and "endangered" elsewhere. The Eastern quoll has become extinct from the mainland, and is only found in Tasmania, where its status, although relatively common, is "threatened". The western quoll is so named because it has become extinct from the eastern states, and is now only found in the far southwestern corner of Western Australia. Its departure from Queensland was basically unnoticed, as from the time of European settlement it was evidently quite scarce.
No. The Northern quoll is restricted to northern Australia. Only the Bronze quoll and the New Guinean quoll are found on the island of New Guinea.
The weight of the avarage northern quoll is 900g which is 2lbs
The quoll is a carnivorous marsupial mammal, of which there are four species, all native to Australia. Western Quoll or Chuditch (Dasyurus geoffroii) is now limited to south-western Western Australia. They are considered to be endangered. Northern Quoll (Dasyurus hallucatus) is the smallest and most aggressive of the quolls. It is limited to coastal regions of northern Australia. They are considered to be endangered. Spotted-tail Quoll or Tiger Quoll (Dasyurus maculatus) is the largest carnivorous marsupial on the mainland. It is limited to coastal regions of eastern Australia and Tasmania. They are considered to be vulnerable in Tasmania and south eastern Australia and endangered in north Queensland. Eastern Quoll (Dasyurus viverrinus) is now endangered on the mainland with no recorded sightings for years. It is still common in Tasmania. They are considered to be secure in Tasmania and endangered on the mainland. All Quoll species are threatened by loss of habitat, viruses, predation by dogs, cats and foxes, and competition from introduced species. The Spotted-tail and Northern Quolls are both being killed off as a result of eating the Cane Toad, which is poisonous.
The spotted tailed quoll is listed nationally as "endangered".In Queensland, it is listed as endangered in the northeast of the state, but vulnerable in the southeast of Queensland.It is also listed as endangered in South Australia, but classified as "vulnerable" in New South Wales and Victoria. In Tasmania it is classified as "rare".The primary threats to the spotted tailed quoll are habitat destruction, and predation by feral animals such as foxes and wild dogs.
The Northern quoll's pouch is formed by folds of skin which protect the joeys.
No.
Not especially. The Northern quoll has no stronger a scent than other native Australian animals.
The quoll is considered threatened or endangered in certain regions of Australia. The Northern Quoll, in particular, is facing significant population declines due to habitat loss, predation by invasive species, and disease. Conservation efforts are being undertaken to protect and preserve these unique marsupials.
Quolls are not in danger of extinction. All Quoll species are threatened by loss of habitat, viruses, predation by dogs, cats and foxes, and competition from introduced species. The Spotted-tail and Northern Quolls are both being killed off as a result of eating the Cane Toad, which is poisonous.Incidentally, not all quolls are classified as endangered.The spotted tailed quoll is endangered only in South Australia and Queensland. It is classified as "vulnerable" in New South Wales, Victoria and Tasmania.The Eastern quoll has not been sighted on the mainland since about 1963, but it is still relatively common in Tasmania, but is classified as "threatened" there.The western quoll, or Chuditch, is extinct in all states except for the far southwestern corner of Western Australia, where it is "vulnerable".The Northern quoll, however, is classified nationally as "endangered", and in the Northern territory it is "critically endangered".
There is a total of four quoll species in Australia. They are the northern, spotted-tailed (also known as tiger quoll), eastern and western quolls.In addition, there are two species of quoll in New Guinea: the bronze quoll and the New Guinean quoll.
