Tasmanian Devil (Sarcophilus harrisii), Endangered

Check out this anthology of 'speculative fiction.' Titled Extinction Doesn't Mean Forever, the stories are themed around extinct or imaginary creatures returning to the modern world. The authors have decided to donate the profits earned between July 1 and July 15, 2011 to help save the Tasmanian Devil.

Download a copy of their book during those two weeks and you can help prevent the extinction of the Tasmanian Devil.

Check out these previous posts on the Tasmanian Devil to learn what's been causing their decline, or check out the Save the Tasmanian Devil website for the latest news and information.

Devils' Hope

Tasmanian Devil (Sarcophilus harrisii)


The Tasmanian Devil, the largest surviving marsupial carnivore, has been dealing with a nasty disease for the past decade. Referred to as Devil Facial Tumour Disease (DFTD), this rare cancer is infectious, meaning it can be passed between individuals. Devils are often violent with each other, and it is believed that the cancer cells are transmitted during such bouts, either during fights over food, or while mating.

Devils contracting the disease develop large cancerous tumours around their face, mouth, and eyes, preventing them from eating or functioning, and usually die within six months. So far, 59% of the island state of Tasmania has been affected by the disease, with a 53% decline in devil populations over the past ten years. Up until recently, no devil had ever survived or shown an immunity to DFTD.

Now, a devil from unaffected western Tasmania, has shown resistance to the disease. After being injected with tumour cells, the three-year-old devil known as Cedric, was able to develop antibodies. Researchers hope that the disease-free western population may be genetically distinct, and that this distinctness may help fight DFTD, either through the development of a vaccine, or through selective breeding, to increase the numbers of devils able to resist the disease.

However, it's not the only hope. Disease free devils have been captured and a captive breeding program is underway, to ensure that disease free populations remain, whatever happens to the wild devil populations. Up to 150 devils will be in captive breeding programs by early next year, both in Tasmania, and in zoos and parks on mainland Australia.

Help the Devils.

Devil Facial Tumour Disease

Tasmanian Devil (Sarcophilus harrisii)

In 1996, the Tasmanian Devil was placed in the category of animals at 'Least Risk' of extinction. In that same year, a few devils were observed and photographed with growths and tumors on their faces. Today, 10 years later, it is estimated that 40% of the Devil population has been wiped out by what has come to be known as Devil Facial Tumour Disease (DFTD). The disease causes large tumours to grow on the faces of the Devils, and once the tumours appear, there is no recovery--at least not yet. Researchers are actively pursuing research to combat DFTD and preserve the threatened population of Devils.

DFTD is transmitted by allograft, which is fairly rare. Allograft occurs when diseased cells are passed physically from one individual to another. In the case of DFTD, it is thought that the cells are passed between individuals during their frequent scuffles, or mating which often involves biting the necks of their partners.

Currently, captive breeding populations have been established to ensure that the species will survive in the event that DFTD causes them to disappear from the wild. There is also concern that competition with introduced species such as foxes will hinder the Devil's ability to recover.

Tasmanian Devils are confined to the island of, well, Tasmania, and are named for their eerie calls (my friends will tell you that at times, I can be convinced to attempt an imitation).
