About the spiny-tailed monitor

The spiny-tailed monitor, also called the ackie monitor, is a small Australian monitor lizard that reaches up to 70 cm in total length. It is found in northern Western Australia, the Northern Territory and western Queensland, where it lives among arid rocky ranges and outcrops. Active by day and usually solitary, it shelters under rock slabs, in crevices and in burrows. It hunts arthropods such as grasshoppers, beetles and spiders, and small lizards make up about a third of its diet. Its dark brown back is spotted with yellowish to cream markings, and the round tail is covered in spiny scales.

AZAThe Association of Zoos and Aquariums. Accredited members have passed an independent inspection of animal care and welfare, safety, conservation and education, repeated every five years. Many smaller facilities never apply, so “not accredited” isn't a verdict on its own. What accreditation means · How we check this
