In Australia, monitor lizards are known as goannas (See main article).
Distribution
The various species of Varanus cover a vast area, occurring through Africa, the Asian subcontinent from India and Sri Lanka to China, down Southeast Asia to Indonesia, the Philippines, New Guinea, Australia and islands of the Indian Ocean and South China Sea.Evolutionary overview
Monitor lizards are considered to be the most derived lizards, possessing a relatively high metabolic rate for reptiles and several sensory adaptations that benefit the hunting of live prey. Recent research indicates that the Varanid lizards, including the Komodo dragon, may have very weak venom.[1] Some monitor lizards are apparently capable of parthenogenesis.[2] Monitor lizards are carnivorous .Origin of the name
The genus name, "Varanus" is derived from the Arabic word waral ورل, which is translated to English as "monitor". It has been suggested that the occasional habit of varanids to stand on their two hind legs and to appear to "monitor" their surroundings led to the original Arabic name.[3] According to legend, these lizards were supposed to warn people that crocodiles were nearby.[4]Apparent intelligence
Varanid lizards are very intelligent, and some species can even count.[4] Careful studies feeding V. albigularis at the San Diego Zoo varying numbers of snails showed that they can distinguish numbers up to six.[4][4][6] V. niloticus have been observed to cooperate when foraging.[6] One varanid lures the female crocodile away from her nest while the other opens the nest to feed on the eggs.[6] The decoy then returns to also feed on the eggs.King, Dennis & Green, Brian. 1999. Goannas: The Biology of Varanid Lizards. University of New South Wales Press. ISBN 0-86840-456-X, p. 43.</ref >V. komodoensis, at the Smithsonian National Zoological Park in Washington, D.C., recognize their keepers and seem to have distinct personalities.[4]M/H2>
Monitor lizards have become a staple in the pet trade. The most commonly kept monitors are the savannah monitor, white throated monitor, and Acklin's monitor, due to their relatively small size and ease of domestication. Nile monitors, water monitors, mangrove monitors, and papau monitors have also been kept in captivity. Like all reptiles that are kept as pets, monitors need hiding places, and an appropriate substrate (bedding). Monitors also need a large water dish in which they can soak their entire body. In the wild, monitors will eat anything they can overpower, but crickets, superworms, and the occasional rodent make up most of the captive monitors' diet. Boiled eggs, silkworms, earthworms, and feeder goldfish can also be fed to monitors. Monitor lizards have been compared to reptillian cats - independent animals with different personalities. However, due to their predatory nature and large size some monitors can be dangerous to keep as pets.
