Adult Tasmanian devils have few natural predators such as eagles, owls, and spotted-tailed quolls, although Tasmanian wolves may have preyed on them historically.

Adult Tasmanian devils have few natural predators, although Thylacines (Thylacinus cynocephalus) may have preyed on them occasionally. Small Tasmanian devils may fall prey to eagles (Accipitridae), owls (Strigiformes), and spotted tail quolls (Dasyurus maculatus).

Tasmanian devils are ferocious when attacked and because they are impressively armed with heavy jaw musculature and robust teeth, they are able to protect themselves against larger predators.

Their nocturnal activity may help them avoid some predators, such as thylacines (Thylacinus cynocephalus), historically.
