The updated Red List of Endangered Species was release in early October and ther 1141 species of threatened mammals on the list. That's 25% and 1 in 2 are facing a shrinking population.
Australia's mammals are the most at risk in the developed world: 59 are threatened which one in five. Fifty of those are found nowhere else. The Tasmanian Devil has been the most surprising move on the endangered list due to a viciously "infectious" facial cancer (if it is infectious is it a cancer?)
Total list is 44838 of which more thatn 38% or 16,928 are at risk and 3000 are critically endangered (the highest category of risk so: vulnerable, endangered and critically endangered).
