Spencer's monitor is a large predatory lizard from Australia. It has a powerful body, a long tail, and sharp claws on strong legs.
Spencer's monitor differs from related species by its large size and adaptation to dry plains. It is important for nature as a predator that controls the population of small animals and cleans the territory from carrion.
Immature form that undergoes metamorphosis before adulthood.
