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 West African Nile monitor, one species is also found in south America 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 such as ''Dampier Peninsula monitor, Varanus sparnus'', to over in the case of the Komodo dragon, though the extinct megalania (''Varanus priscus'') may have reached lengths of more than . Most monitor species are terrestrial locomotion, terrestrial, but many are also arboreal or semiaquatic. While most monitor lizards are carnivorous, eating smaller reptiles, fish, birds, insects, small mammals, and eggs, a few species also eat fruit and vegetation.

Varanus Albigularis
The rock monitor (''Varanus albigularis'') is a species of monitor lizard in the family Varanidae. The species is endemic to Sub-Saharan Africa, where, on average it is the largest lizard found on the continent. It is called ''leguaan'' or ''likkewaan'' in some areas. Taxonomy First described by François Marie Daudin in 1802, ''V. albigularis'' had been classified as a subspecies of '' V. exanthematicus'',. but has since been declared a distinct species, based on differences in hemipenal morphology. The generic name ''Varanus'' is derived from the Arabic word ''waral'' ورل (English: "monitor"). The specific name ''albigularis'' comes from a compound of two Latin words, ''albus'' (meaning "white") and ''gula'' ("throat").

Varanus Salvadorii
The crocodile monitor (''Varanus salvadorii''), also known as the Papuan monitor or Salvadori's monitor, is a species of monitor lizard endemic to New Guinea. It is the largest monitor lizard in New Guinea and is one of the longest lizards, verified at up to . Its tail is exceptionally long, with some specimens having been claimed to exceed the length of the Komodo dragon, however less massive. Crocodile monitors are arboreal lizard with a dark green body marked with bands of yellowish spots. It has a characteristic blunt snout and a very long prehensile tail. It lives among the mangrove swamps and coastal rainforests of the southeastern part of New Guinea, feeding opportunistically on everything from birds and small mammals to eggs, other reptiles, amphibians and carrion. Its large, backwards-curving teeth are better adapted than those of most monitors for seizing fast-moving prey. Like all monitors, it has anatomical features that enable it to breathe more easily when running ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Varanus Griseus
The desert monitor (''Varanus griseus'') is a species of monitor lizard of the order Squamata found living throughout North Africa and Central and South Asia.

Varanus (Varanus)
''Varanus'', commonly known as true monitors, is one of the 11 subgenus, subgenera of the genus ''Varanus''. All of its species are found in the Australasian realm, among which are the world's largest lizards. Within this subgenus, the Monophyly, monophyletic clade comprised ''Yellow-spotted monitor, V. panoptes'', ''Sand goanna, V. gouldii'', ''Rosenberg's monitor, V. rosenbergi'', and ''Spencer's goanna, V. spenceri'' are collectively known as sand monitors. Description True monitors are characterized by their wide skulls and strong jaws, with the nostrils cranially positioned on the sides of their snout. Their teeth are curved, serrated and concealed by thick lips, making them invisible even if their mouths are open. Their tongues are forked like a snake's, which they use to pick up scent. Like all monitors, they have slender, elongated necks. The tails are heavy and muscular, being thick at the base and laterally compressed towards the end. Most true monitors have lean bo ...

Varanus Prasinus
The emerald tree monitor (''Varanus prasinus'') or green tree monitor, is a small to medium-sized arboreal monitor lizard. It is known for its unusual coloration, which consists of shades from green to turquoise (color), turquoise, topped with dark, wikt:transverse, transverse wikt:dorsal, dorsal banding. This coloration helps camouflage it in its arboreal habitat. Its color also makes the emerald tree monitor highly prized in both the pet trade and zoos alike. Names It is known as wbl km in the Kalam language of Papua New Guinea. Taxonomy ''Varanus prasinus'' was first described as ''Monitor viridis'' by John Edward Gray in 1831; however, Gray's original holotype (RMNH 4812 in the Naturalis, National Natural History Museum in Leiden) was lost and the species was redescribed by Schlegel eight years later as ''V. prasinus'' using the found specimen.

Varanidae
The Varanidae are a family of lizards in the superfamily Varanoidea and order Anguimorpha. The family, a group of carnivorous and frugivorous lizards, includes the living genus '' Varanus'' and a number of extinct genera more closely related to ''Varanus'' than to the earless monitor lizard (''Lanthanotus''). ''Varanus'' includes the Komodo dragon (the largest living lizard), crocodile monitor, savannah monitor, the goannas of Australia and Southeast Asia, and various other species with a similarly distinctive appearance. Their closest living relatives are the earless monitor lizard and Chinese crocodile lizard. The oldest members of the family are known from the Late Cretaceous of Mongolia. Taxonomy The Varanidae were defined (using morphological characteristics) by Estes, de Queiroz and Gauthier (1988) as the clade containing the most recent common ancestor of '' Lanthanotus'' and ''Varanus'' and all of its descendants. A similar definition was formulated by Conrad ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Lizard
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic islands, oceanic Archipelago, island chains. The grouping is Paraphyly, paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling ''Draco (genus), Draco'', are able to glide. They are often Territory (animal), territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
