The lace monitor (Varanus varius), also known as the tree goanna, is a member of the monitor lizard family native to eastern Australia. A large lizard, it can reach 2 metres (6.6 ft) in total length and 14 kilograms (31 lb) in weight.
The lace monitor is the second-largest of all goannas, reaching lengths up to 2 m (6.6 ft). Other more common tree goannas, such as the Timor tree monitor ( V. timorensis ) and mournful tree monitor ( V. tristis ,) do not grow to quite such lengths, typically a maximum of 61 cm, nose-to-tail.
Yellow-spotted monitor (left), lace monitor (right) This ground dwelling monitor species, somewhat resembles the widespread sand goanna (Varanus gouldii).Large, dark spots appear in rows along its back, becoming especially distinct at the center of the back where they are interspersed with smaller and paler spots.
Monitor lizards are lizards in the genus Varanus, the only extant genus in the family Varanidae. They are native to Africa, Asia, and Oceania, and one species is also found in the Americas as an invasive species. [1] About 80 species are recognized. Monitor lizards have long necks, powerful tails and claws, and well
Spencer's goanna has unusual defensive behaviour, where it feigns death when threatened; the body is flattened against the ground, one hind limb is extended while all other limbs held close to the body, and the tail is contorted into a wavy shape. The head is kept up to observe the threat, feigning death until the threat has left the area.
Bites on the hand by Komodo dragons (V. komodensis), perenties (V. giganteus), lace monitors (V. varius), and spotted tree monitors (V. scalaris) have been observed to cause swelling within minutes, localised disruption of blood clotting, and shooting pain up to the elbow, which can often last for several hours.

Varanoidea is a superfamily of lizards, including the well-known family Varanidae (the monitors and goannas). Also included in the Varanoidea are the Lanthanotidae (earless monitor lizards), and the extinct Palaeovaranidae. Throughout their long evolutionary history, varanoids have exhibited great diversity, both in habitat and form.
In some places, however, the ranges of Gould's monitor, V. g. flavirufus and the Argus monitor overlap. The similarities between the species and their close proximity frequently cause confusion. The sand monitor is a relentless forager. It is diurnal, meaning most of its activities take place during the day. Anything smaller than itself will be ...
