Burton's Nessia
''Nessia burtonii'', commonly known as Burton's nessia, Gray's snake skink, or the three-toed snake skink, is a species of skink, a lizard in the family Scincidae. The species is endemic to the island of Sri Lanka. Etymology The specific name, ''burtonii'', is in honor of British army surgeon Edward Burton (1790–1867).Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Nessia burtonii'', p. 43). Habitat and geographic range A burrowing skink found in the wet zone of Sri Lanka, ''N. burtonii'' is widely distributed at at Gampola, Veyangoda, Lunawa, Mathugama, Kuruwita, Rakwana, and Kadugannawa. Description ''N. burtoni'' has 24-26 scale rows at midbody. The body is slender and of equal girth from head to tail. The snout is acute. Each limb has three tiny clawed toes, hence one of the common names. The dorsum is brown or light reddish brown, each scale with a darker e ...

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] |

Reptiles Of Sri Lanka
This is a list of reptiles of Sri Lanka. The reptilian diversity in Sri Lanka is higher than the diversity of other vertebrates such as mammals and fish with 181 reptile species. All extant reptiles are well documented through research by many local and foreign scientists and naturalists. Sri Lankan herpetologist, Anslem de Silva largely studied the biology and ecology of Sri Lanka snakes, where he documented 96 species of land and sea snakes. Five genera are endemic to Sri Lanka - ''Aspidura'', ''Balanophis'', ''Cercaspis'', ''Haplocercus'', and ''Pseudotyphlops''. Out of them only five of the land snakes are considered potentially deadly and life threatening to humans. Among snakes, 54 are endemic to Sri Lanka. The total increased to 107 with new descriptions of ''Dendrelaphis'', ''Rhinophis'', ''Aspidura'' and ''Dryocalamus''. Lizard diversity in the island has been documented and studied by many local scientists and researchers such as Imesh Nuwan Bandara, Kalana Maduwage, Anj ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthworm
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each s ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Kadugannawa
Kadugannawa is a town in Kandy District in the Central Province, Sri Lanka, Central Province of Sri Lanka, governed by an Urban Council. It is located along the A1 road west of Peradeniya. The town is served by Kadugannawa Railway Station and has the Kadugannawa Central College. Museum Since 2014 it is the location of the National railway museum, Kadugannawa, national railway museum. Kadugannawa Pass Kadugannawa Pass is a pierced rock in the Kadugannawa climb on the Kandy-Colombo road. In the 1820s when the British built the Kandy-Colombo road they pierced a rock at the Kadugannawa Pass instead of blasting it away or simply bypassing it, as the new road does today. An explanation is, that this Kadugannawa tunnel was a symbol. The tunnel is said to have been created to fulfil an old Sinhalese prophecy that there is no way for foreigners to rule Kandy unless they pierce the mountains. The British were the first foreign power to occupy Kandy permanently. Thus, the British went ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
