Taxonomy
A description of the species was presented to the Royal Society of Victoria in 1895 by Arthur H. S. Lucas and Charles Frost.[1]
Distribution
Varanus eremius is the most widespread of the pygmy goannas. It lives in desert and semidesert areas of South Australia, Western Australia, and the Northern Territory. Its range possibly includes Queensland, as well.;[7][8] Storr & Harold 1980).
Description
The rusty desert monitor reaches a total length of about 50 cm.[2] The colouration of this monitor lizard on the upper side is light to dark reddish-brown with numerous, irregularly distributed, black or deep-brown spots. Sometimes, smaller primrose or cream-colored spots are present. Its tail shows alternating cream-colored and deep-brown longitudinal stripes, which are often broken up into scattered spots at the tail base. A conspicuous black stripe occurs from the snout to the eye.[2]
Behaviour
This species spends its life on the ground and seldom climbs trees. No successful breeding in captivity has yet been reported.[2]
Diet
Stomach contents indicate the diet by volume of the rusty desert monitor consists mainly of other lizards (76%). The remainder of animals eaten by this monitor include large grasshoppers and occasional scorpions.[9]
