Spiny-tailed Monitor

(Varanus acanthurus)

Spiny-tailed Monitors (ackies) have experienced a huge surge in popularity in Australian collections where they are being touted as an ideal beginner monitor and great pet lizard. The popularity of these animals is justifiable as they are of a manageable size, display good temperaments and are generally easy to care for. They should be maintained on a primarily insect diet with the occasional high protein item, such as pink mice. Due to the wide distribution of this species it can be highly variable in colouration and pattern. The first two specimens pictured here are from the brachyurus sub-species, and are commonly referred to as "Yellow Ackies". "Red ackies" are from the acanthurus sub-species and occur in the western part of the range.
