Varanus (Odatria)
The subgenus ''Odatria'', sometimes known as the dwarf monitor lizards, consists of small monitor lizards found in Australia and Indonesia. Species in this subgenus include the smallest monitor species in the world, the tiny 16 gram Dampier Peninsula monitor, but also includes some more medium sized species such as the 240 gram black-palmed rock monitor. Taxonomy ''Odatria'' was coined by John Edward Gray in 1838, albeit as a genus name. ''Odatria'' is the most species diverse subgenus of monitor lizards, with 22 different species. The subgenus also includes two species complexes represented by the spiny-tailed monitor and the Timor monitor. Alternatively, Vidal ''et al.'' 2012 splits ''Odatria'' into two species groups represented by the spiny-tailed monitor and the black-headed monitor. In the past, tree monitors such as the green tree monitor have sometimes been included within ''Odatria'' as well as ''Euprepriosaurus'', but now form their own subgenus ''Hapturosa ...

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 ...

Varanus Scalaris
''Varanus scalaris'' is a small species of monitor lizard. It is often referred to as the banded tree monitor or the spotted tree monitor. It is found in Australia in the states of Western Australia and Queensland as well as the Northern Territory, the province of Papua, Indonesia and in Papua New Guinea. The species inhabits trees in the savanna A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to ... woodlands and forages for food in both trees and on the ground, with a diet consisting of insects as well as small vertebrates.

Varanus (Hapturosaurus)
The subgenus ''Hapturosaurus,'' sometimes known as the tree monitors, consists of slender-bodied arboreal monitor lizards mostly found in the tropical rainforests of Indonesia and Papua New Guinea. Taxonomy The type species is the green tree monitor, originally designated by Hermann Schlegel in 1844 as ''Monitor prasinus''. Robert Mertens placed tree monitors within the subgenus ''Odatria'' in 1942. In 1988, tree monitors were instead placed within '' Euprepriosaurus'' alongside the mangrove monitors. Nevertheless, there was a distinction between mangrove and tree monitors that was clear even then, so ''Euprepriosaurus'' was commonly considered to consist of two species complexes, i.e., the '' V. indicus'' complex and the '' V. prasinus'' complex. In 2016, Yannick Bucklitsch, Wolfgang Böhme, and André Koch found the two species complexes sufficiently morphologically, ecologically, and biologically distinct, and so all species within the ''V. prasinus'' complex were moved und ...

Emerald Tree Monitor
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, topped with dark, transverse 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 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. The generic name ''Varanus'' is derived from the Arabic word ''waral'' (ورل), which translates to English as "monitor". Its specific name, ''prasinus'', is Latin for the color green. ' ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic Generic or generics may refer to: In business * Generic term, a common name used for a range or class of similar things not protected by trademark * Generic brand, a brand for a product that does not have an associated brand or trademark, other ... name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of ...

Black-palmed Rock Monitor
The black-palmed rock monitor (''Varanus glebopalma'') is a member of the Varanidae family found in Australia. Also known as the twilight monitor or the long-tailed rock monitor, it is a member of the subgenus ''Odatria'', and is found in the northern part of Australia in the Northern Territory and Western Australia, as well as Queensland. Specifically, its distribution extends from Mount Isa in the east to the Kimberleys in the west. Its habitat is areas of rock escarpment, and large populations may be found in small areas. Taxonomy A species first described in 1955 by South Australian curator Francis John Mitchell, nominating the holotype as a specimen obtained at Lake Hubert in the Northern Territory. Mitchell's specimen was the only example available, and was shot by R. R. Miller near a sandstone outcrop during the 1948 American-Australian Scientific Expedition to Arnhem Land. The new species was allied to the infrageneric classification ''Varanus'' (''Odatria''). Common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Black-headed Monitor
The black-headed monitor or black-tailed monitor (''Varanus tristis'') is a relatively small species of monitor lizards native to Australia. It is occasionally also called the mournful monitor, freckled monitor (''Varanus tristis orientalis'') or the racehorse monitor, a name it shares with the Gould's monitor due to their exceptional speed. It is placed in the subgenus ''Odatria''. Nomenclature Its specific name, ''tristis'', means "sad", in reference to the completely black colouration of ''V. t. tristis'' populations around Perth. Distribution This is the most widespread monitor species in Australia, occurring throughout the mainland and even on some northern islands such as Magnetic Island Magnetic Island ( Wulguru: Yunbenun) is an island offshore from the city of Townsville, Queensland, Australia. This mountainous island in Cleveland Bay has effectively become a suburb of Townsville, with 2,335 permanent residents. The islan .... It is only absent in the southernm ...

Varanus Timorensis
''Varanus timorensis'', the Timor monitor or spotted tree monitor, is a species of small monitor lizards native to the island of Timor and some adjacent islands. Taxonomy Kimberley rock monitors (''Varanus glauerti''), Varanus scalaris, banded tree monitors (''Varanus scalaris''), and Varanus similis, spotted tree monitors (''Varanus similis'') were once considered subspecies of the Timor monitor, but have since been elevated to full species status. Currently, the peacock monitor (''Varanus auffenbergi'') is sometimes considered a subspecies, but is usually considered its own species. Description The Timor monitor is a dwarf species of monitor lizard belonging to the subgenus ''Odatria''. Generally, it is dark greenish-gray to almost black in background color, with bright gold-yellow or sometimes bluish spotting along its Dorsum (anatomy), dorsal surface and a lighter straw-yellow color on its ventral side. It has a pointed snout, excellent eyesight and hearing, sharp teeth, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
