they eat smaller animals
Goannas, which are large monitor lizards of Australia, are not endangered. However, due to increased numbers of cane toads in the "Top end" (far northern region of the Northern Territory), which are poisonous to any goannas which try to eat them, there are fears that goannas will soon be endangered in that region.
In the ground
Holroyd-Parramatta Blacktown AFC Goannas was created in 1979.
Because part of their natural diet is carrion (dead animals). They find the carcasses by using their sense of smell - and will 'home in' on an animal from some distance away.
Goannas, which are large monitor lizards found in Australia, may prey on various small animals, including reptiles. However, thorny devils, known for their spiky armor and unique defensive adaptations, are not a common part of their diet. While it is possible for a goanna to attempt to eat a thorny devil, the latter's spines and ability to camouflage make it a less appealing target. Thus, while not impossible, it is not typical for goannas to eat thorny devils.
