Devil Facial Tumor Disease is one of only three known types of contagious cancers (none of which are found in humans). Tasmanian devils transmit it to one another by biting—a common behavior among the marsupials. The cancer causes facial tumors that eventually eliminate the devil's ability to eat. It seems to have a 100% mortality rate in infected animals, and has killed the majority of the wild Tasmanian devil population.
