One of the biggest blows to conservation efforts came in the 1990s when a communicable cancer called devil facial tumor disease — which passes between devils through their bites while mating and causes large tumors that prevent them from eating — reduced the population from some 140,000 to as few as 20,000.
In response, researchers established an insurance population of cancer-free devils in wild-type enclosures in Australia’s island state of Tasmania. But the releases in July and September are the first time the squat mammals — all of which have tested negative for the contagious cancer — have been released on the mainland in a protected wild landscape.
"Bites while mating." Have you seen their teeth?
