The Lace Monitor, or Lace Goanna, "Varanus varius", is a member of the
monitor lizardfamily, Australian members of which are commonly known as goannas.
Lace Monitors, are also known as Lace Goannas in
Australiaand are the second-largest monitor in Australia after the Perentie. They can be as long as 2.1 metres (over 6ft 10ins) with a head and body length of up to 76.5 cm (2½ ft). The tail is long and slender and about 1.5 times the length of the head and body. [Ehmann, Harald. "Encyclopedia of Australian Animals: Reptiles", p. 158. (1992). The Australian Museum. ISBN 0-207-17379-6 ("Reptiles").] ["Wildlife of Tropical North Queensland: Cooktown to Mackay", p. 233. (2000). Queensland Museum. ISBN 0-7242-9349-3] Maximum weight of lace monitor can be 20 kg., but most adults are much smaller.
These common terrestrial and often
arborealmonitors are found in eastern Australia and range from Cape Bedfordon Cape York Peninsulato south-eastern South Australia. They frequent both open and closed forests and forage over long distances (up to 3 km a day).
They are mainly active from September to May, but are inactive in cooler weather and shelter in a
tree hollowor under a fallen tree or large rock.
The females lay from 4 to 14 eggs in spring or summer in termite nests. They frequently attack the large
compostingnests of Scrub Turkeys to steal their eggs, and often show injuries on their tails inflicted by male Scrub Turkeys pecking at them to drive them away.
Their patterning consists of white spots, blotches or bands on their body. Their distribution is chiefly coastal. Their diet typically consists of insects, reptiles, small mammals, birds and birds' eggs.
Like all Australian goannas, they were a favourite traditional food of
Australian Aboriginalpeoples and their fat was particularly valued as a medicine and for use in ceremoniesFact|date=June 2007.
In late 2005,
University of Melbourneresearchers discovered that Perenties ("Varanus giganteus") and other lizards, may be somewhat venomous. Previously, it had been thought that bites inflicted by these lizards were simply prone to infection because of bacteria in the lizards' mouths, but these researchers have shown that the immediate effects are caused by mild envenomation. Bites on human digits by a Lace Monitor("Varanus varius"), a Komodo Dragon("V. komodoensis") and a Spotted Tree Monitor("V. scalaris") have been observed and all produced similar results in humans: rapid swelling within minutes, localised disruption of blood clotting, shooting pain up to the elbow, with some symptoms lasting for several hours.
