Rena Boettgeri
''Rena boettgeri'', also known commonly as the Baja California Cape wormsnake and the Cerralvo Island threadsnake, is a species of snake in the family Leptotyphlopidae. The species is endemic to Baja California, Mexico. Geographic range The Cerralvo Island threadsnake is found in the Cape Region of Baja California Sur. This species appears to be absent from the higher elevations of the Sierra La Laguna. It is also found on Isla Cerralvo in the Municipality of La Paz. Etymology ''R. boettgeri'' is named in honor of German herpetologist Oskar Boettger. Description ''R. boettgeri'' has the following scalation. The rostral is rounded at the back, taking up about 1/3 the width of the head and almost reaching between the eyes. The nasal is completely divided, with the nostril near the rostral. The ocular reaches the edge of the upper lip between two supralabials, the front of which is just as high but narrower than the rear. There are 4 lower lip shields. There are 14 scales arou ...

Franz Werner
Franz Josef Maria Werner (15 August 1867 in Vienna – 28 February 1939 in Vienna) was an Austrian zoologist and explorer. Specializing as a herpetologist and entomologist, Werner described numerous species and other taxa of frogs, snakes, insects, and other organisms. His father introduced him at age six to reptiles and amphibians. A brilliant student, he corresponded often with George Albert Boulenger (1858–1937) and Oskar Boettger (1844–1910) who encouraged his studies with these animals. Werner obtained his doctorate in Vienna in 1890 and then after spending a year in Leipzig, began to teach at the Vienna Institute of Zoology. In 1919, he became tenured as a professor, maintaining this title until his retirement in 1933. Although working close to the Vienna Natural History Museum, he could not use their herpetological collections, after the death of its director, Franz Steindachner (1834–1919), who did not like Werner, and had barred him from accessing the collection ...

Rostral Scale
The rostral scale, or rostral, in snakes and other scaled reptiles is the median plate on the tip of the snout that borders the mouth opening. Wright AH, Wright AA (1957). ''Handbook of Snakes of the United States and Canada''. Ithaca and London: Comstock Publishing Associates. (7th printing, 1985). 1,105 pp. (in two volumes). . It corresponds to the mental scale in the lower jaw. The term pertains to the rostrum, or nose. In snakes, the shape and size of this scale is one of many characteristics used to differentiate species from one another.

Reptiles Of Mexico
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...

Rena (genus)
''Rena'' is a genus of snakes in the Family (biology), family Leptotyphlopidae. The genus is Endemism, endemic to the New World. All of the species were previously placed in the genus ''Leptotyphlops''. Species The genus ''Rena'' contains the following species, which are recognized as being valid. *''Rena boettgeri'' *''Rena bressoni'' – Michoacán slender blind snake *''Rena dugesii'' – Alfredo Dugès, Dugès's threadsnake *''Rena dulcis'' – Texas blind snake *''Rena humilis'' – western threadsnake *''Rena iversoni'' *''Rena klauberi'' *''Rena maxima'' – giant blind snake *''Rena segrega'' – Trans-Pecos blind snake *''Rena unguirostris'' – southern blind snake ''Nota bene'': A Binomial nomenclature, binomial authority in parentheses indicates that the species was originally described in a genus other than ''Rena''. Etymologies The specific name, ''dugesii'', is in honor of Mexican zoologist Alfredo Dugès. The specific name, ''iversoni'', is in honor of ...

William Roy Branch
William Roy "Bill" Branch (12 May 1946, London, England – 14 October 2018, Port Elizabeth, South Africa) was a British-South-African herpetologist. Branch studied at the University of Southampton where he remained until completing his Ph.D. degree (''Studies on a foetal-specific alpha-globulin FPin the rabbit'' ). From 1972 he worked as a scientist in the Life Sciences Division of the Atomic Energy Board in Pretoria doing research on, inter alia, liver cancer, but returned to the University of Southampton in 1976 to take up a post-doctoral research fellowship in the Department of Biology studying the synthesis of chemicals in the liver of foetal rabbits. He started working at Port Elizabeth Museum in 1979 and retired in 2011, when he was appointed as Research Associate and Curator Emeritus. Over a period of almost 40 years he conducted field work in about 20 African countries and played a major role in building up the large reptile and amphibian collections at the Museum. Publ ...

Monochrome
A monochrome or monochromatic image, object or palette is composed of one color (or values of one color). Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog). In physics, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which is a distinct concept. Application Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype ("blueprint") images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image. In computing, monochrome has two meanings: * it may mean having only one color which is either on or off (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. 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 axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Supralabials
In reptiles, the supralabial scales, also called upper-labials, are those scales that border the mouth opening along the upper jaw. They do not include the median scaleWright AH, Wright AA. 1957. Handbook of Snakes. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . (rostral scale). The term '' labial'' originates from (Latin for "lip"), which refers to any lip-like structure. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another.
