If there was the opportunity, a dingo might eat a Tasmanian devil. However, there are several reasons why it would be extremely unlikely:
No. Although both carnivorous mammals, this is where the similarity between Tasmanian devils and dingoes stops. Tasmanian devils are marsupials, with a pouch in which they rear their young. Dingoes are relative "newcomers" to Australia, and placental mammals.
Tasmanian devils do not eat other live Tasmanian devils. They will, however, readily feed on the carcass of another Tasmanian devil that has died.
Tasmanian devils are not edible though they would have been eaten by the Tasmanian Aborigines. It would also be illegal to try to eat them.
Tasmanian devils eat possums
powerful, rufous owl, wedge tailed eagle, tasmanian devil, dingo, foxes and python will kill and eat cockatoos
If the two species occupies the same continent, which they do not, then a tiger could very easily eat a Tasmanian devil. Currently, there are no opportunities for tigers to consume Tasmanian devils.
The Tasmanian devil has particularly strong jaws which are powerful enough tobute through bones.
A Tasmanian devil can eat about 15% of its body weight a day, but it will eat up to 40% of its body weight in 30 minutes if the chance arises.
If there were stoat in Tasmania, which there are not, it is likely that the Tasmanian devil would eat them, if the opportunity arose. Tasmanian devils favour small mammals, but the stoat could possibly be too quick and fierce to be caught.
There is no "co-animal" for the Tasmanian devil. It is a solitary species that does not interact with other species, except to hunt and eat them.
Any animal larger than a wallaby will not be attacked or hunted by a Tasmanian devil. However, there is no limit to the size of an animal it will eat if the animal is already dead, as the Tasmanian devil is a scavenger as well as a hunter.
The Tasmanian devil's only native competitor for food is the quol. However, the quoll is a much smaller dasyurid, and is certainly not a competitor for the carrion which Tasmanian devils eat. Foxes have been introduced fairly recently into Tasmania, and they, too, are competition for the Tasmanian devil.
