SYDNEY (AFP) – Australia's Tasmanian devil, the world's largest surviving marsupial carnivore, will be listed as endangered because of a contagious and deadly cancer, the government said.
"This disease has led to the decline of about 70 percent of the Tasmanian devil population since the disease was first reported in 1996," Environment Minister Peter Garrett said in a statement.
Devil facial tumour disease, which is spread through biting, kills the animals usually within three months by growing over their faces and mouths, preventing them from eating.
Early European settlers named the feisty marsupial the devil for its spine-chilling screeches, dark appearance and reputed bad temper which, along with its steeltrap jaw, made it appear incredibly fierce.
The animals were previously listed as vulnerable, and Garrett said the change in status to endangered would give them greater protection under national environment law.
"Fortunately, strong action is being taken to find out more about this disease and to stop its spread," he said.
The government had committed 10 million dollars (7.5 million US) over five years to a program aimed at saving the devil, including research into the disease and support for captive and wild populations, he said.
The species is restricted to the island state of Tasmania after competition from the dingo led to its extinction on mainland Australia.
It is Australia's largest marsupial carnivore after the extinction last century of its distant cousin, the thylacine or Tasmanian tiger.
Tasmanian devils listed as endangered in Australia

CANBERRA, Australia – The Tasmanian devil, a snarling fox-sized marsupial made notorious by its Looney Tunes cartoon namesake Taz, was listed in Australia as an endangered species Friday because of a contagious cancer that has wiped out most of the wild population.
The upgrade from "vulnerable" under Australian environmental law entitles the world's largest marsupial carnivore to greater protection in the island state of Tasmania, Environment Minister Peter Garrett said in a statement.
Devils do not exist in the wild outside Tasmania, although mainland zoos are breeding captive populations as a strategy against total extinction.
Their numbers have declined by 70 percent since the facial cancer was first reported in 1996. The disease is caused by bites inflicted on each other's faces as part of a bizarre mating ritual or while squabbling over food. It causes grotesque facial tumors that eventually prevent them from feeding, leading to starvation within months.
"Strong action is being taken to find out more about this disease and to stop its spread," Garrett said.
The government has already committed 10 million Australian dollars ($7.8 million) over five years to research the disease and support captive breeding programs, but scientists say more is needed.
Hamish McCallum, senior scientist in the government-backed devil rescue program, said the main advantage of the endangered listing was that it acknowledged the serious threat the species faced.
"I'm hoping that it might cause a philanthropist or corporate sponsors to say: 'Hey, this is serious' and to chip in some serious money," McCallum said.
"I guess my optimism has diminished a little bit, but I'm still hopeful that of the various angles we're looking at, one of them will come through and we won't lose the animals in the wild," he added.
Warner Bros., which owns Taz, and CNN founder Ted Turner, who started the Cartoon Network, have helped fund the fight against the disease.
McCallum fears that devils could be extinct in the wild in 20 years. He estimates there are as few as 10,000 now, as the cancer continues to spread west and south across Tasmania.
Scientists have been working since the disease first emerged to save the animals, known for their powerful jaws and bloodcurdling growl.
Programs to try to save them include plans to relocate breeding pairs to island sanctuaries and to protect disease-free populations on peninsulas with devil-proof fences several miles (kilometers) long.
McCallum said he is frustrated that disagreement among scientists has prevented the sanctuaries from being established on islands off Tasmania. Some scientists fear the introduced devils would threaten endangered birds.
Scientists had hoped to find a genetic solution to the disease through a young devil who showed signs of natural immunity in laboratory tests. But that devil last year contracted a second, mutated strain of the cancer.
A test that can potentially detect the disease in a devil before it becomes contagious is in trials. While scientists hope this will help keep small wild populations disease free, the test is not yet proven to be accurate.
