Xenopeltis Unicolor
:''Common names: sunbeam snake, common sunbeam snake, iridescent snake.Mehrtens JM. 1987. ''Living Snakes of the World in Color''. New York: Sterling Publishers. 480 pp. .'' ''Xenopeltis unicolor'' is a non-venomous sunbeam snake species found in Southeast Asia and some regions of Indonesia. This is a primitive snake known for both its highly iridescent scales and its ability to reproduce quickly, as it is oviparous and as such can lay up to 10 eggs at a time. No subspecies are currently recognized. Description Grows to an average of about 1 m (3 ft 3 in). A fossorial species, the head is wedge-shaped and narrow with little neck delineation, which makes it easy to push through the soil. Its most defining characteristic is its iridescent, highly polished scales that give this snake its common name. They have a layer of dark pigmentation just below the surface on each scale that enhances the iridescence. The youngs look very similar to the adults, except that they have a ...

Caspar Georg Carl Reinwardt
Caspar Georg Carl Reinwardt (5 June 1773 in Lüttringhausen – 6 March 1854 in Leiden) was a Prussian-born Dutch botanist. He is considered to be the founding father of Bogor Botanical Garden in Indonesia. Biography In 1787 he was apprenticed to an Amsterdam pharmacy where his brother worked. He came in contact with several scientists, including the botanist Gerardus Vrolik (father of Willem Vrolik). He had his education at the Athenaeum Illustre where he successfully engaged in the study chemistry and botany. Under the Batavian Republic and the Kingdom of Holland he served as a professor of natural history at the University of Harderwijk from 1800 to 1808. After a while he became associate professor of chemistry and pharmacy. In 1808 he appealed to king Louis Bonaparte and was offered work as director of the "to be built" botanical and zoological gardens and museums. In 1808 he became a member of the Royal Institute of the Netherlands. And in 1810 just before the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Iridescent
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. It is a kind of structural coloration that is due to wave interference of light in microstructures or thin films. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and a ...

Andaman Islands
The Andaman Islands () are an archipelago in the northeastern Indian Ocean about southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar. The Andaman Islands are home to the Andamanese, a group of indigenous people that includes a number of tribes, including the Jarawa and Sentinelese. While some of the islands can be visited with permits, entry to others, including North Sentinel Island, is banned by law. The Sentinelese are generally hostile to visitors and have had little contact with any other people. The government protects their right to privacy. History Etymology In the 13th century, the name of Andaman appears in Late Middle ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John C. Wells, John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: [ˈmjænmɑː, ˈbɜːmə]. So the pronunciation of the last syllable of Myanmar as [mɑːr] or of Burma as [bɜːrmə] by some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad a, broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

The Pythonidae, commonly known as pythons, are a family of nonvenomous snakes found in Africa, Asia, and Australia. Among its members are some of the largest snakes in the world. Ten genera and 42 species are currently recognized. Distribution and habitat Pythons are found in sub-Saharan Africa, Nepal, India, Bangladesh, Sri Lanka, Southeast Asia, southeastern Pakistan, southern China, the Philippines and Australia. In the United States, an introduced population of Burmese pythons, ''Python bivittatus'', has existed as an invasive species in the Everglades National Park since the late 1990s.

Boidae
The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific Islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Five subfamilies, comprising 12 genera and 49 species, are currently recognized. The Old Tupi name for such snakes was mbói, which figures in the etymology of names such as ''jibóia'' and ''boitatá'' (the Brazilian name for the mythical giant anaconda). Description Like the pythons, boas have elongated supratemporal bones. The quadrate bones are also elongated, but not as much, while both are capable of moving freely so when they swing sideways to their maximum extent, the distance between the hinges of the lower jaw is greatly increased.Parker HW, Grandison AGC. 1977.

Color Vision
Color vision, a feature of visual perception, is an ability to perceive differences between light composed of different wavelengths (i.e., different spectral power distributions) independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of photoreceptors by light entering the eye. Those photoreceptors then emit outputs that are propagated through many layers of neurons and then ultimately to the brain. Color vision is found in many animals and is mediated by similar underlying mechanisms with common types of biological molecules and a complex history of evolution in different animal taxa. In primates, color vision may have evolved under selective pressure for a variety of visual tasks including the foraging for nutritious young leaves, ripe fruit, and flowers, as well as detecting predator camouflage and emotional states in other pr ...
