All varanids are carnivorous and active predators. Gould’s goannas eat primarily mammals and reptiles but will also eat birds, amphibians, reptile eggs, insects, and crustaceans. Much of the vertebrate portion of their diet is probably scavenged from animals killed on the road. The goanna forages over long distances and often digs for prey in loose soil and decaying vegetation. They obtain most of their water from their food. Goannas walk with their snout held close to the ground while hunting for food. The long forked tongue flickers in and out transferring scents to the Jacobson’s organs. This way they can rapidly locate hidden prey, even if it is underground. They then use their sharp claws as well as their snout to dig out the prey. Cannibalism also occurs in the Gould’s goanna. Often this involves feeding on carrion.
