Perentie
The perentie (''Varanus giganteus'') is the largest monitor lizard or goanna native to Australia. It is one of the largest living lizards on earth, after the Komodo dragon, Asian water monitor, crocodile monitor, and intersecting by size with Nile monitor. Found west of the Great Dividing Range in the arid areas of Australia, it is rarely seen, because of its shyness and the remoteness of much of its range from human habitation. The species is considered to be a least-concern species according to the International Union for Conservation of Nature. Its status in many Aboriginal cultures is evident in the totemic relationships, and part of the Ngiṉṯaka dreaming, as well as bush tucker. It was a favoured food item among desert Aboriginal tribes, and the fat was used for medicinal and ceremonial purposes. Taxonomy British zoologist John Edward Gray described the perentie in 1845 as ''Hydrosaurus giganteus'', calling it the "gigantic water lizard". George Albert Boulenger mo ...

List Of Largest Extant Lizards
Currently there are about 40 extant families of Lacertilia. These vary considerably, e.g. in shades, colours, and sizes. For example, the largest representative among Geckos, the New Caledonian giant gecko (''Rhacodactylus leachianus''), has a length of up to 36 cm (14 in), while the largest species in the family Varanidae, Komodo dragon (''Varanus komodoensis''), has a length up to 3 metres (10 ft), and a body mass of 70 kg (154 lbs). Largest extant lizards Here are the 15 largest extant lizards based on the most reliable measurements for size, including length and weight. These include family types Varanidae, Iguanidae and Teiidae exceeding 9 kg (20 lbs) in mass. By families Agamas (Agamidae) *The largest representatives in this group are species in the genus ''Hydrosaurus'', which often exceed 1 metre (3.3 ft) in length. **The largest species – Makassar salfin lizard (''Hydrosaurus microlophus'') and Sulawesi black salfin lizar ...

Monitor Lizard
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. About 80 species are recognized. Monitor lizards have long necks, powerful tails and claws, and well-developed limbs. The adult length of extant species ranges from in some species, to over in the case of the Komodo dragon, though the extinct varanid known as megalania (''Varanus priscus'') may have been capable of reaching lengths more than . Most monitor species are terrestrial, but arboreal and semiaquatic monitors are also known. While most monitor lizards are carnivorous, eating eggs, smaller reptiles, fish, birds, insects, and small mammals, some also eat fruit and vegetation, depending on where they live. Distribution The various species cover a vast area, occurring through Africa, the Indian subcontinent, to China, the Ryukyu Islands in southern J ...

Goanna
A goanna is any one of several species of lizards of the genus '' Varanus'' found in Australia and Southeast Asia. Around 70 species of ''Varanus'' are known, 25 of which are found in Australia. This varied group of carnivorous reptiles ranges greatly in size and fills several ecological niches. The goanna features prominently in Aboriginal mythology and Australian folklore. Being predatory lizards, goannas are often quite large, or at least bulky, with sharp teeth and claws. The largest is the perentie (''V. giganteus''), which can grow over in length. Not all goannas are so large; pygmy goannas may be smaller than the arm of an adult human. The smallest of these, the short-tailed monitor (''V. brevicauda''), reaches only in length. They survive on smaller prey, such as insects and mice. Goannas combine predatory and scavenging behaviours. They prey on any animal they can catch that is small enough to eat whole. They have been blamed by farmers for the death of sheep, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squamate
Squamata (, Latin ''squamatus'', 'scaly, having scales') is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the dwarf gecko (''Sphaerodactylus ariasae'') to the Reticulated python (''Malayopython reticulatus'') and the now-extinct mosasaurs, which reached lengths over . Among other reptiles, squamates are most closely r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ngiṉṯaka
Ngiṉṯaka (), also spelled Ngintaku, is a giant perentie lizard Ancestral Being from Aṉangu and Pitjantjatjara religion and mythology. It is associated with Angatja, an area along an important songline. Ngiṉṯaka is one of the two major reptile Ancestral Beings associated with Uluru, the other being Milpali. Myth Ngiṉṯaka's songline is known as ''Inma Ngiṉṯaka''. It tells of his journey of the creation of over 500 km via a song whose stanzas follow his travels through the land. In the songline, Ngiṉṯaka is presented with human characteristics. In the myth, Ngiṉṯaka travels from his home near the Western Australia border to the camp of another lizard tribe, near Oodnadatta, in search of a better grindstone. He stole the Anangu grindstone and carried it home, chased by the Anangu people. In one spot along his journey, he digs up tjanmatjas (bush onions), creating large boulders. As he traveled, he created many landforms in the Musgrave and Mann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venomous
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a stinger, in a process called envenomation. Venom is often distinguished from poison, which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and toxungen, which is actively transferred to the external surface of another animal via a physical delivery mechanism. Venom has evolved in terrestrial and marine environments and in a wide variety of animals: both predators and prey, and both vertebrates and invertebrates. Venoms kill through the action of at least four major classes of toxin, namely necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and haemotoxins, which disrupt blood clotting. Venomous animals cause tens of thous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argus Monitor
The yellow-spotted monitor (''Varanus panoptes''), also known as the Argus monitor, is a monitor lizard found in northern and western regions of Australia and southern New Guinea. Taxonomy The first description of the species was provided in a revision of the varanids of Western Australia, where the family is represented by diverse taxa in a wide variety of habitats. Early collections and descriptions of the region's species have historically been uncertain, leading the ICZN to issue an opinion that related to this taxon. A third subspecies was published in 1988, based on specimens from southern New Guinea. The describing author discovered that the specimen selected as the type of ''Varanus gouldii'' was in fact assignable to this species, recently described by reptile specialist Glenn Storr. By issuing an opinion on the various taxonomic considerations, the voting members conserved the name published with John Edward Gray's description and stabilised the nomenclature of this spe ...

Crocodile Monitor
''Varanus salvadorii'', also known as the crocodile monitor, Papuan monitor and Salvadori's monitor, is a species of monitor lizard endemic to New Guinea. It is the largest monitor lizard known from New Guinea, and is one of the longest lizards in the world, verified at up to . The tail of the species is exceptionally long, so some specimens have been claimed to exceed the length of the world's largest lizard, the Komodo dragon; however, ''V. salvadorii'' is far less massive. ''Varanus salvadorii'' is an arboreal lizard with a dark green body marked with bands of yellowish spots. It has a characteristic blunt snout and a very long tail. It lives in mangrove swamps and coastal rainforests in the southeastern part of the island, feeding on birds, small mammals, eggs, and carrion. Its teeth are better adapted than those of most monitors for seizing fast-moving prey. Like all monitors, ''V. salvadorii'' has anatomical features that enable it to breathe more easily when running than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lace Monitor
The lace monitor or tree goanna (''Varanus varius'') is a member of the monitor lizard family native to eastern Australia. A large lizard, it can reach in total length and in weight. The lace monitor is considered to be a least-concern species according to the International Union for Conservation of Nature. Taxonomy John White, the surgeon-general of New South Wales, described this species as the variegated lizard (''Lacerta varia'') in 1790. George Shaw reported that several specimens were taken back to England. French naturalist François Marie Daudin gave it the name ''Tupinambis variegatus'' in 1802, and noted two forms. German naturalist Blasius Merrem established the genus '' Varanus'' in 1820, with ''V. varius'' as the first mentioned member set as its type species by John Edward Gray in 1827. French zoologists André Marie Constant Duméril and Gabriel Bibron described two specimens in 1836, one in their possession and one from the collection of English zoologist Th ...
