The Spiny-tailed Monitor or Ridge-tailed Monitor (varanus acanthurus) is a small species of monitor lizard. They are native to Northwestern Australia and live in a variety of habitats from arid to tropical regions. Spiny-tailed Monitors are usually a reddish brown with yellow markings but color and pattern can vary with geographic origin. A distinctive feature is their thick spined tail - hence their common name. This tail is used for both attacking prey and for protection from predators. When attacking prey the tail is used like a whip, stunning the prey item which is then consumed without expending further effort. When used in defense, the Ridge-tail will scramble into loose rocks or boulders and use its tail to wedge itself in tight. The spikes give the tail good grip on the rocks, making extraction by other predators nearly impossible. In the species' home territory, the tail is often found discarded near Ridge-tail carcasses, indicating that predators of this species consider the tail inedible.
Their diet consists mainly of insects and small lizards.
There are several subspecies including:
Varanus acanthurus brachyurus, Common Ridge-tailed Monitor, or Yellow Ackie
Varanus acanthurus insulanicus, Island Ridge-tailed Monitor
