摘要

塔斯马尼亚魔鬼,Sarcophilus harrisii (Boitard, 1842),现存最大的有袋类食肉动物,是塔斯马尼亚特有的。S. harrisii体型像一只矮小的狗,雄性重9公斤,雌性重6公斤,是大型哺乳动物的食腐动物和脊椎动物的机会性捕食者。野外的平均寿命为3-4年,直到20世纪90年代末,一种由叮咬传播的致命癌症开始摧毁种群,主要是成年。恶魔面部肿瘤病(DFTD)是一种软组织肿瘤,通常首先出现在头部,总是在症状出现后6个月内死亡。在DFTD出现后的20年里,哈里斯虫已经从一个“最不受关注”的物种变成了一个“受威胁”的物种,并有可能走向灭绝

Sarcophilus harrisii (Dasyuromorphia: Dasyuridae)
The Tasmanian devil, Sarcophilus harrisii (Boitard, 1842), the largest surviving marsupial carnivore, is endemic to Tasmania. The size of a small stocky dog, with males weighing 9 kg and females 6 kg, S. harrisii is a scavenger of large mammals and opportunistic predator of vertebrates. Life span in the wild averaged 3–4 years until the late 1990s when a fatal cancer, transmitted by bites, began devastating populations, primarily adults. Devil Facial Tumor Disease (DFTD), a soft-tissue neoplasm usually seen 1st on the head, invariably kills within 6 months of the appearance of symptoms. In the 20 years since the appearance of DFTD, S. harrisii has gone from a species of "Least Concern" to one "Threatened" and potentially on the path to extinction
