most iconic species, but is threatened by a number of different diseases and human processes which make its continued existence unclear. The species was declared endangered in 2008 following the outbreak of the Devil Facial Tumour Disease (DFTD), which has spread through the species in the past 8 years¹.
- Devil Facial Tumour Disease
The disease is usually transmitted when one devil bites another which is infected, directly receiving the infection. Other transmission methods include consumption of an infected carcass or sharing food.
The disease usually begins as lumps or sores around the lips and mouth of the devil, and spreads rapidly. Cancerous tumours develop around the face which often spread over the entire body. Once a devil has been infected with the disease, it usually dies within six months due to organ failure, secondary infection, or starvation caused by the inability to feed².
There have been some developments in treating and preventing the disease, which does give hope to remaining devils. Some devils have been found which appear to have resistance to the disease, leading to hopes that they can recover and that a new population can be developed. Disease free populations have been isolated on both Maria Island and in a facility near Hobart. Captive breeding programs are in progress throughout both Tasmania and mainland Australia, which are designed to preserve the genetic variability of the species².
Unfortunately, this isn’t the only thing which threatens the continued existence of the Tasmanian devil. There are a number of other threats which also affect population numbers, or which have in the past, including:
- Introduced Predators
- Habitat Loss and Fragmentation
Tasmanian devils are the animal which everyone knows from popular media. However, they are likely to go extinct by 2035 if a cure for the DFTD is not found².
