Key Differences
The perentie is known for its impressive size, often exceeding 2.5 meters in length and is considered the largest monitor lizard in Australia. On the other hand, the term goanna is used more broadly to describe various species of monitor lizards found throughout Australia, which vary significantly in size.
Perenties are distinguished by their robust bodies and powerful limbs, adapted for digging and climbing. Whereas, goannas cover a wider variety of physical forms, from the robust tree-dwelling lace monitor to the sleeker, ground-dwelling sand goanna.
The perentie inhabits arid, desert regions of Central and Western Australia, thriving in these harsh environments. In contrast, goannas as a group occupy a diverse range of habitats, from tropical rainforests to sandy deserts across the continent.
Perenties are solitary creatures, largely relying on their size and speed for defense and hunting. Goannas, however, exhibit a range of behaviors from the highly arboreal and social lace monitor to the more reclusive sand goanna.
Perenties have a diet that primarily consists of larger prey due to their size, including small mammals, birds, and eggs. Goannas have more varied diets, which can include everything from insects and carrion to larger vertebrates, depending on the species and environmental availability.
