why is the tasmanian devil a keystone species
The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial found in the wild only in the Australian island state of Tasmania. After the extinction in 1936 of the Tasmanian tiger (or Thylacine), another well-known carnivorous marsupial, the Tasmanian devil became the largest carnivorous marsupial in the world.
