Goannas
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, tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-tailed Monitor
The short-tailed pygmy monitor (''Varanus brevicauda'') is the second smallest living monitor lizard in the world with a maximum length of 25 cm. Distribution The short-tailed monitor ranges throughout central Australia from the coast of Western Australia through the interior of Northern Territory and northwestern South Australia to western Queensland. This monitor burrows in compacted sandy loam and gravel, in areas dominated by spinifex (''Triodia'' spp.). This terrestrial species is secretiveVaranus brevicauda mampam.com and rarely seen active above ground; it is mainly encountered by digging up its burrow.

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 moved ...

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 ...

Sand Goanna
The sand goanna (''Varanus gouldii'') is a species of large Australian monitor lizard, also known as Gould's monitor, sand monitor, or racehorse goanna. Taxonomy John Edward Gray described the species in 1838 as ''Hydrosaurus gouldii'', noting the source of the type specimen as "New Holland" and distinguishing the new varanid by "two yellow streaks on the sides of the neck" and small flat scales at the orbits. An earlier description, ''Tupinambis endrachtensis'' Péron, F. 1807, was determined as likely to refer to this animal, but the epithet ''gouldii'' was conserved and a new specimen designated as the type. This neotype was obtained in 1997 at the near coastal Western Australian suburb of Karrakatta, and placed with the British Museum of Natural History. The decision of a nomenclatural commission (ICZN) was to issue an opinion suppressing the earlier names, ''Tupinambis endrachtensis'' and ''Hydrosaurus ocellarius'' Blyth, 1868, that were unsatisfactory to some who had comm ...

Mangrove Monitor
The mangrove monitor, mangrove goanna, or Western Pacific monitor lizard (''Varanus indicus'') is a member of the monitor lizard family with a large distribution from northern Australia and New Guinea to the Moluccas and Solomon Islands. It grows to lengths of . Names It is known as wbl yb in the Kalam language of Papua New Guinea. Taxonomy The mangrove monitor was first described by the French herpetologist François Marie Daudin in 1802. Daudin's original holotype of a subadult specimen was collected on Ambon, Indonesia, and has since disappeared from the museum in Paris. Daudin's original name for the species was ''Tupinambis indicus'', an appellation it would carry for 100 years until being renamed as a ''Varanus''. The generic name ''Varanus'' is derived from the Arabic word ''waral'' (ورل), which translates to English as "monitor." Its specific name, ''indicus'', is Latin for the country of India, but in this instance it relates to Indonesia or the East Indies, where ...

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around ...

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 Japan, s ...

Spiny-tailed Monitor
The spiny-tailed monitor (''Varanus acanthurus''), also known as the Australian spiny-tailed monitor, the ridge-tailed monitor the Ackie's dwarf monitor, and colloquially simply ackie monitor, is an Australian species of lizard belonging to the genus of monitor lizards (''Varanus''). Description The spiny-tailed monitor, a somewhat small monitor lizard, can attain a total length of up to 70 cm (27 in), although there are unconfirmed reports of wild individuals growing up to 34 inches. The tail is about 1.3-2.3 times as long as the head and body combined. The upper side is a rich, dark brown and painted with bright-yellowish to cream spots, which often enclose a few dark scales. Its tail is round in section and features very spinose scales. There are 70-115 scales around the middle of the body. The spiny-tailed monitor is distinguished from the similar-looking species '' V. baritji'' and '' V. primordius'' by the presence of pale longitudinal stripes on the neck. Dist ...

Mertens' Water Monitor
Mertens' water monitor (''Varanus mertensi''), also called Common name, commonly Mertens's water monitor, and often misspelled Mertin's water monitor, is a species of lizard in the Family (biology), family Varanidae. The species is Endemism, endemic to northern Australia, and is a wide-ranging, actively foraging, opportunistic predator of aquatic and Riparian zone, riparian habitats. It is named after German herpetologist Robert Mertens. Description ''Varanus mertensi'' grows to a total length (including tail) of about . It is dark brown to black above, with many cream to yellow spots. The underparts are paler – white to yellowish – with grey mottling on the throat and blue-grey bars on the chest. The tail is strongly compressed laterally, with a high median dorsal keel, and is about 1.5 times the length of head and body. Distribution and habitat Mertens' water monitor is found in coastal and inland waters across much of northern Australia, from the Kimberley (Western Aust ...

Phalangeriformes
Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas (the term comes from Powhatan language ''aposoum'' "white animal", from Proto-Algonquian *''wa·p-aʔɬemwa'' "white dog"). However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos. Phalangeriformes are quadrupedal diprotodont marsupials with long tails. The smallest species, indeed the smallest diprotodont marsupial, is the Tasmanian pygmy possum, with an adult head-body length of and a weight of . The largest are the two species of bear cuscus, which may exceed . Phalangeriformes species are typically nocturnal and at least partially arbo ...
