The first recorded instance of DFTD began in the 1990s. DFTD means the Tasmanian Devil facial tumour disease, a fatal condition which causes cancers around the face and head of Tasmanian Devils. It first appears as small lesions and lumps around the animal's mouth which grow quite quickly, inhibiting the Devil's ability to feed. They slowly starve to death, whilst their their bodily functions gradually break down. It spreads from animal to animal through them biting each other, and given that this is natural behaviour for Devils, it means that the disease can quickly spread through a population.
It is not known for certain what initiated DFTD. Tasmanian devils, being restricted now to just the Australian island of Tasmania, have limited genetic diversity in their wild population. The disease is believed to have started from a chance mutation in the far north east region of Tasmania, in Mount William National Park. Other theories have suggested this is a result of the Devils' weaker immune system not being able to cope with the pesticides used in agriculture.
In 2010, an international team of scientists discovered that cells which protect peripheral nerves are probably to blame for the Devil Facial Tumour Disease. These cells, known as Schwann cells, have provided the necessary information about the genetic marker resnsible for the disease, and have helped scientists move closer to discovering a vaccine.

∙ 12y agoThe Tasmanian devil is endangered for many reasons; one early reason for the Tasmanian devil's population decline was extermination by farmers. The farmers believed that devils were eating their livestock and poultry. Not knowing that the devils are carnivorous which results then to mainly feed on carrion and carcasses, and very small birds, reptiles and insects. It was also noticed that as the devils fed of the road-killed animals found on the roads it led then to often be hit by cars, causing a decline in the population. The arrival of the dingos also caused a competition in the source of food, which caused the extinction on the devils on the mainland. The later reason that came to be known was a facial tumour that spread like an infection. It was transmitted through bite and as a result caused the formation of large tumours on the face and neck of the infected Tasmanian devil. The tumours made it impossible for them to eat causing many to die through starvation. This caused a major decline in the population, which till now no one knows what the cause of the disease is

Why are Tasmanian devils in danger?
Tasmanian devils are at risk from several factors:Habitat loss through increased housing developments and industry, especially logging.They are carrion-eaters and scavengers, often being killed by cars when feasting on road kill.Young Tasmanian devils are at risk from introduced species such as foxes and wild dogs.The main threat to the Tasmanian devil is the Devils Facial Tumour disease, which cause large cancers to form on the animal's face, especially around its mouth. This prevents the Tasmanian devil from feeding properly, and it slowly starves to death. Scientists are still working on a cure.
Tasmanian Devils are native to which continent?
Tasmanian Devils are native to the continent of Australia. They are no longer found on the mainland, though fossil evidence indicates that they did live on the main continent prior to the introduction of the dingo. Tasmanian devils are now found only on Australia's island state of Tasmania, which lies to the south of the mainland.
On what continent does the Tasmanian devil originate?
Tasmanian Devils originated on the continent of Australia.They are no longer found on the mainland, though fossil evidence indicates that they did live on the main continent prior to the introduction of the dingo. Tasmanian devils are now found only on Australia's island state of Tasmania, which lies to the south of the mainland
What do kangaroos koalas and Tasmanian devils have in common?
Kangaroos, koalas and Tasmanian Devils have two main things in common.They are all marsupial mammals, meaning they give birth to undeveloped young which must then remain in the mother's pouch for several months.They are all native to the country of Australia.
What is being done to save Tasmanian devils from being endangered?
One of the main threats to the Tasmanian devil is the Devil Facial Tumour Disease. Scientists are breeding Tasmanian Devils in captivity to limit the spread of the Devil Facial Tumour Disease (DFTD). This disease is a great threat to Tasmanian devils living in the wild, affecting some two-thirds of the population. The Australian Government now has initiatives and programs set up to preserve the species. Tasmanian devils are being housed in captive breeding programmes, which should prevent the extinction of the marsupial, but not necessarily in the wild. In January 2010, a team of international scientists pinpointed the genetic marker that predisposes Tasmanian devils towards this fatal disease. With this knowledge, there is now a better chance of a cure, which would also stop the disease decimating the wild Tasmanian devil population.
Who hunts the Tasmanian Devil babies?
The main danger to Tasmanian devil joeys comes from introduced foxes and domestic dogs. Birds of prey such as falcons and goshawks may also take young devils.
What do Tasmanian devils eat that are dangerous for us?
They may be dangerous when provoked and can cause bites and wounds to an adult human but are not critically dangerous. They are mostly scavengers and do not attack prey that is larger than young Kangaroos. Tasmanian devils, despite their reputation, are actually timid and shy creatures which would rather hide from people than confront them. They never attack people, but will certainly defend themselves, and they have exceptionally powerful jaws.
What are the enemies of the Tasmanian Devil?
The Tasmanian Devil had no natural predators until introduced species such as cats, dogs and foxes were brought to Tasmania.A major enemy of the Tasmanian devils is human beings. See the related Wikipedia link below.
What methods are used to conserve the Tasmanian devils?
The main method being used to help conserve the Tasmanian devil for the future is captive breeding programmes, which breed Tasmanian devils safely away from other devils which have the fatal Devil Facial Tumour Disease. Moves to breed more genetically diverse Tasmanian devils with higher levels of immunity have been very successful. Plans are afoot to release healthy Tasmanian devils onto islands off Tasmania, where they can help to improve the biodiversity of those islands. In January 2010, a team of international scientists pinpointed the genetic marker that predisposes Tasmanian devils towards this fatal disease. With this knowledge, there is now a better chance of a cure, which would also stop the disease decimating the wild Tasmanian devil population. Research continues into finding a cure. In addition, the "Save the Tasmanian Devil" was begun, with the objective being to 'maintain an enduring and ecologically functional population of Tasmanian Devils in the wild in Tasmania'. This programme is a joint initiative between the Australian Federal and Tasmanian State governments, together with the University of Tasmania. More sponsorship has come through the car company Suzuki Australia which has developed a is partnership with Zoos Victoria. Suzuki donates an amount from the sale of each Suzuki SUV to help save the Tasmanian Devil.
Why are Tasmanian devils' habitat under threat?
The Tasmanian devil's habitat is eucalypt forest, woodlands, heath and even farmland (due to land clearing). The main reason its habitat is under threat is as a result of land clearing and logging. Tasmanian forests are continually being harvested for timber.
Why isn't anything being done about the Tasmanian devil?
On the contrary: a great deal is being done to try and help the Tasmanian devil. One of the main threats to the Tasmanian devil is the Devil Facial Tumour Disease. Scientists are breeding Tasmanian Devils in captivity to limit the spread of the Devil Facial Tumour Disease (DFTD). This disease is a great threat to Tasmanian devils living in the wild, affecting some two-thirds of the population.

Why did Tasmanian devils leave main land Australia?
Tasmanian devils are only found in the wild in the Australian state of Tasmania. They are believed to have become extinct from the mainland continent about 400 years ago. For many years it was thought that the reason for the loss of the mainland Tasmanian devil was increased competition from the dingo, which was introduced by the Aborigines. However, scientists now challenge this idea, believing that a combination of environmental changes (such as increasing aridity) and climate change caused the Tasmanian devil to die out on the mainland.
