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] |
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 ''Hapturosau ...

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 zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Reptiles Of Timor
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 31 ...
