SYDNEY (Reuters) - A mysterious cancer is killing Australia's
Tasmanian devils, whose spine-chilling screeches, dark color and
reputed bad temper prompted early settlers to give them their chilling
name, wildlife officials said on Thursday.

The world's largest carnivorous marsupial is the size of a stocky
small dog but has jaws as strong as a crocodile which allow it to eat
up to half its body weight in 30 minutes. An adult can weigh up to 26
pounds.

On Australia's southern island state of Tasmania -- the only place
where you can find Tasmanian devils -- they are the dominant predator
but are now being stalked by a disease that has cut some population
groups by 85 percent.

Wildlife officials said the Tasmanian devil (Sarcophilus harrisii)
population peaked at around 150,000 to 200,000 in 1996 when the cancer
first appeared, but they now fear the cancer may kill two thirds of
the population by 2006.

The disease has spread widely in the eastern and central parts of
Tasmania over the last two years, causing huge tumors that block the
animals' eyesight, hearing or mouths, leaving them unable to feed and
starving to death. "We suspect it spreads by biting when the animals
quarrel or mate sexually," said Nick Mooney, a wildlife biologist with
the nature conservation branch of the state's wildlife department.

The disease, thought to be caused by a virus, will not wipe out the
devil as such diseases often spare a few isolated animals who
reproduce and replenish the population.

"We may find there is nothing more we can do than isolate parts of the
population," Mooney said
