Tasmanian Devils fight Contagious Cancer
During the last 20 years, a contagious cancer has decimated Tasmanian devil (Sarcophilus harrisii) populations. Cancer cells, which are spread by biting, grow deadly tumors on the faces and mouths of the aggressive marsupials. Because devil facial tumor disease (DFTD) has been observed in almost all known populations and is nearly 100 percent fatal, epidemiological models have suggested that the most long-infected populations are facing extinction.
