http://www.fossilnews.com/1995/varanus.html

Extractions: Monitor lizards or goannas (family Varanidae) are common in tropical and subtropical areas of the globe today, consisting of almost three dozen species spread across Africa, Asia, the East Indies, and Australia. The largest is the ferocious, 3-meter Komodo dragon (Varanus komodoensis) which will eat livestock and humans; most varanids are smaller (though still fairly large as lizards go a meter or two long), and feed on small animals, molluscs, insects, and eggs. The first fossils of the genus Varanus are found in Africa in the Early Miocene, while the family Varanidae has a fossil history extending back into the Cretaceous of Mongolia. The nearest living relatives of modern goannas are the earless monitor Lanthanotus, an obscure southeast Asian lizard, and the gila monster and beaded lizard of the genus Heloderma. The true monitor lizards form a cohesive group that is easily identifiable by their streamlined shape, elongated neck, semi-erect posture, and forked tongue. They inhabit a variety of econiches ranging from savannah to woodland to riparian habitats. Those monitors which spend a lot of time in the water have tall neural spines on their tail vertebrae. This makes the tail tall and flat so that it is useful as an organ of propulsion. The earliest known member of the genus, Varanus rusingensis from the Miocene of Kenya, also had such a tail and was probably semiaquatic like the Nile monitor

Extractions: OTHER MONITOR LIZARDS There are dozens of species of monitor lizards found in Africa, Asia, Indonesia, New Guinea, and Australia. Indian Monitors are thought to have been transported by natives to the Polynesian Islands, possibly as a food source. Monitors have a unique ability to greatly increase the size of the mouth cavity enabling them to swallow their prey whole. The Nile Monitor will lay eggs in termite mounds which provide a natural incubation! The Earless Monitor is a semiaquatic lizard that is native to Borneo. Lizards (along with some other reptiles) continue growing their entire life.

It would be expected that long-lived monitor lizards attained even greater size under the optimal conditions of the early earth. In fact, the skeleton of a 20 foot giant monitor lizard, Megalania, has been discovered in Australia. It probably weighed about two tons and hunted giant kangaroos!

Extractions: Members of the Varanidae family are more often called monitor lizards. They are found in Africa, Southern Asia, Indo-Australia, and Australia. Their habitat ranges from arid desert to tropical rainforest. Varanids have a small head, long neck, stout body, and long tails. A good portion of their length is tail. They range in size from 10 inches to 10 feet. They are meat eaters and what they eat depends on the size of the lizard. Most varanids are terrestrial-arboreal predators . There are some that hunt primarily in water. They are also egg layers.

http://www.cyclura.com/article/articleview/147/1/3/

Extractions: An extract from my Little Book of Monitor Lizards As the monitors spread across the Earth experiencing different habitats and climates they diversified. Over many millions of years this process has resulted in the emergence of at least seventy or eighty (probably many thousands of) species. Some of them appeared to have died out quickly, whilst other, apparently ancient, species have survived until the present. Many monitor lizards appear to have evolved comparatively recently. According to the available evidence monitor lizards and their close relatives the heloderms (Gila lizards) and lanthonotids (earless monitors) probably originated in northern Asia at least 90 million years ago (Pregill et al 1986). At this time the reign of the dinosaurs was coming to an end and flowers had begun to cover the Earth. The oldest monitor lizards known are from Mongolia: Telmasaurus grangeri Saniwides mongoliensis and Estesia mongoliensis . All of them must have been quite similar to modern monitor lizards in appearance, but the latter possessed grooved teeth which probably transmitted venom in the same manner as modern-day Gila monsters (Pregill et al 1986, Norell et al 1992). The exact relationship between these lizards and the modern heloderms and varanids is not clear.

Extractions: An extract from my Little Book of Monitor Lizards Our relationship with monitor lizards stretches back over 90,000,000 years. For almost all of this time they have been the predators and we the prey. The first documented cases of predation on monitor lizards by humans date back about 40,000 years (King 1962). Today mankind's relationship with the monitors is a complex one. They are undou-btedly the most important of the lizards to the human race. Monitors are often said to have provided the inspiration for mythological dragons, but many other animals have equally strong claims. Marco Polo's description of the Great Serpents of Karazan could easily refer to a Komodo dragon: "Here are great serpents ten paces in length and ten spans the girth of the body. At the forepart near the head they have two short legs, each having three claws like those of a tiger, with eyes larger than a four-penny loaf and very glaring. The jaws are wide enough to swallow a man, the teeth are large and sharp and their whole appearance is so formidable that neither man nor any other animal can approach them without terror." Folklore is rich in superstitions and anecdotes concerning monitor lizards. In some places they are despised or even feared, but many cultures appreciate the lizards and some hold them in great reverence.

http://www.nafcon.dircon.co.uk/varanids1.html

Extractions: Last updated 9 January 2002: added navigation links. A few things need to be borne in mind relating to the diet of monitor lizards. Firstly, monitors in general are hearty eaters, especially when acclimatised, and will often eagerly go for food. Do not take this as a sign that they are always hungry: the lizards of this genus are among those creatures of the world which find it hard to resist food (and that includes some of the human race!). Seriously, obesity or overfeeding is one of the biggest health problems of monitors in captivity, especially the savannah monitor V. exanthematicus . The problem is often compounded by the fact that tame monitors often spend hours doing little other than laying in their cage and generally doing nothing. While this is to be preferred to non-tame monitors thrashing about, it means that tame captives get a minimal amount of exercise, and diet should be kept to a fairly austere level accordingly. Secondly, while monitors are good feeders, most in the wild do eat other things than rodents, and some have marked preferences toward such prey items as crustaceans, fish or birds. Dietary considerations are obviously dependent upon species, but keepers should be prepared to experiment somewhat. Tinned cat or dog food is an acceptable treat on an occasional level but should not be offered as a regular meal as it is too rich. Dead chicks will often be taken by larger monitors.

Extractions: Superfamily Varanoidea Appearance: All living varanids share a small head, long neck, sturdy body and limbs, and long, powerful tail. Distribution Old World tropics: Africa, Asia, Australia. Habitat Arid or desert areas to tropical rain forest. Size 23 cm (pygmy goanna, Varanus brevicauda ) to 3.1 m (Komodo dragon , V. komodensis ) total length (however, the tail makes up most of the animal). Fossil monitors are estimated to have been 6 meters long! Reproduction Oviparous. Their courtship is often preceded by rirualized male combat, that is, an upright grappling/dancing posture. Food All varanids are carnivores, although the Philippine butaans ( V. olivaceus ) seasonally eat fruit. The smaller species prey mainly on insects, small reptiles, and amphibians. With increasing body sizes, prey preference shifts increasingly to larger vertebrates, including mammals. Behaviour Most species are terrestrial-arboreal predators, searching for prey in trees as well as on the ground. Some species (

Extractions: Chicago Herpetological Society Title: Living Dragons: A Natural History of the World's Monitor Lizards Author: Rodney Steel Reviewed by: Raymond Hoser About Amazon.com Reprinted from the Bulletin of the Chicago Herpetological Society [32(12):255-256, December 1997] I tell everyone I like death adders ( Acanthophis antarcticus ) more than any other reptile on earth. Well now I'm about to let a secret out of the closet. I cried and cried when forced to relinquish my seven lace monitors ( Varanus varius ) in the early 1980s, when my parents sold the family house. Although the lizards went to a good home, they were truly pets in the real sense of the wordmore like dogs and cats than a "reptile." Some of them were even thought to be older than I was! I'd actually inherited some from another man who'd suffered the same fate as me some years earlier. School teacher John Baker caught four adult lace monitors at Bingarra, northwest New South Wales, in the 1960s and kept them at his suburban Sydney home until his parents sold it in the mid-1970s. He knew I'd just built a massive goanna pit at my St. Ives house so he gave me his beloved pets to guard with my life. Nearly ten years later I was doing the same thing. This time these lizards were being passed on to herpetologist Ken Sheppherd to guard with his life. If I had my time again, I'd never have let the lizards go, but then again if I had kept them, they would probably have been taken with the rest of my collection, when it was stolen in July 1984.

ISBN 0-89464-897-7 Reviewed by: David Blatchford About Amazon.com Reprinted from the Bulletin of the Chicago Herpetological Society [32(10):214, October 1997] Monitors are impressive animals. Anyone who has ever watched one of these dramatic animals vigorously patrolling its domain cannot fail to appreciate their presence, vigor and intelligence. In addition their metabolism and anatomy mark them apart from their reptile brethren. Whilst the sheer bulk of many of the family single them out from other lizards, what is also notable is the economy of design. For despite the fact that there are some 70 named forms, they all look more or less the same save for size; no other genus of terrestrial animal demonstrates such a huge range of body sizesspanning five orders of magnitude! They are an ancient form and it seems that their much vaunted resemblance to snakes is a consequence of convergent evolution. Harold De Lisle is a professor of biology at Moorpark College in California and a well-known name in herpetological circles. His particular passion is for monitors, and this scholarly monograph is testament to his extensive reading and knowledge. This book sets a high standard and makes an impressive addition to herpetological literature. The first half of the text is a comprehensive synthesis of current knowledge and at the same time points out just how little is known of these imposing animals. Most of the information stems from studies of just six or seven species, which comes as a surprise when one considers the general level of interest in monitors and their importance in the lizard world.

Extractions: The "Water Monitor", Varanus sp ., is the largest lizard found in the Philippines, growing up to 2-1/2 meters, and is a cousin of the Komodo Dragon. It is locally known as "bayawak" and is sometimes called a "chicken lizard" because it may feed on chicken eggs or chicks. Monitors are opportunistic feeders and scavengers and eat a variety of small animals, insects, fish, molluscs and carrion. As their name implies, they prefer living near fresh or salt- water bodies and are good swimmers. Varanid lizards are widely distributed throughout the Philippines with at least two species: V. olivaceus (Gray's Monitor) and V. salvator , (Water Monitor) with several subspecies. Although fairly common, monitors are at risk due to habitat destruction and unregulated hunting. According to a varanid expert, Eric Pesci: The top photo is of the nominate Varanus salvator salvator or water monitor. The second (middle) photo is of the majestic Mindanao Water Monitor - Varanus salvator cumingi - reproductively isolated to Mindanao and Basilan. This lizard is so beautiful and so close to extinction yet no one seems to care. It has been hunted for skins and to this day - even with a government ban on reptile exports - the lizard is still obtained for leather manufacturers in Asia and Europe.

Extractions: MAIN PAGE MONTH-IN-REVIEW Research by UMass Biologist Suggests that Monitor Lizards Offer "Evolutionary Freeze-Frame" Results reported in Science AMHERST, Mass. Research by Elizabeth Brainerd, of the biology department at the University of Massachusetts, addresses a long-standing disagreement among scientists regarding how lizards breathe. The study, conducted along with colleagues at Harvard University and the University of California, is detailed in the current issue of the prestigious journal, Science. The work was funded by the University of Massachusetts, the National Science Foundation, and a Chapman Fellowship. Brainerd's specialty is biomechanics with an emphasis on evolution. Her work focuses on breathing in lizards. This particular study focused on breathing in green iguanas and monitor lizards. Researchers took X-ray videos of the lizards while the animals walked on treadmills. For years, researchers have disagreed about whether lizards can run and breathe at the same time. The iguana uses chest muscles for both running and breathing, and so is unable to run and breathe simultaneously. This results, Brainerd says, in "a skittering-type locomotion." Many other kinds of lizards are believed to face the same constraint.
