Guanaco Meteorite
The guanaco (; ''Lama guanicoe'') is a camelid native to South America, closely related to the llama. Guanacos are one of two wild South American camelids, the other being the vicuña, which lives at higher elevations. Etymology The guanaco gets its name from the Quechua word ''huanaco'' (modern spelling ''wanaku''). Young guanacos are called ''chulengos''. Characteristics Guanacos stand between at the shoulder, body length of , and weigh . Their color varies very little (unlike the domestic llama), ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small, straight ears. The lifespan of a guanaco can be as long as 28 years. Guanacos are one of the largest terrestrial mammals native to South America today.San Diego Zoo's Animal Bytes Other terrestrial mammali ...

Philipp Ludwig Statius Müller
Philipp Ludwig Statius Müller (25 April 1725 – 5 January 1776) was a German zoologist. Statius Müller was born in Esens, and was a professor of natural science at Erlangen. Between 1773 and 1776, he published a German translation of Linnaeus's '' Natursystem''. The supplement in 1776 contained the first scientific classification for a number of species, including the dugong, guanaco, potto, tricolored heron, umbrella cockatoo, red-vented cockatoo, and the enigmatic hoatzin. He was also an entomologist. Müller died in Erlangen. He is not to be confused with Salomon Müller (1804–1864), also an ornithologist, or with Otto Friedrich Müller Otto Friedrich Müller, also known as Otto Friedrich Mueller (2 November 1730 – 26 December 1784) was a Danish naturalist and scientific illustrator.

Tierra Del Fuego
Tierra del Fuego (, ; Spanish for "Land of the Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands. The southernmost extent of the archipelago is just north of latitude 56°S. The earliest known human settlement in Tierra del Fuego dates to approximately 8,000 BC. Europeans first explored the islands during Ferdinand Magellan's expedition of 1520. ''Tierra del Fuego'' and similar namings stem from sightings of the many bonfires that the natives built. Settlement by those of European descent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penguins And Guanaco
Penguins (order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy penguin, which stands around tall and weighs . Today, larger penguins generally inhabit colder regions, and smaller penguins inh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lama Guanicoe
Lama (; "chief") is a title for a teacher of the Dharma in Tibetan Buddhism. The name is similar to the Sanskrit term ''guru'', meaning "heavy one", endowed with qualities the student will eventually embody. The Tibetan word "lama" means "highest principle", and less literally "highest mother" or "highest parent" to show close relationship between teacher and student."lama" from Historically, the term was used for venerated spiritual masters or heads of .

Cashmere Wool
Cashmere wool, usually simply known as cashmere, is a fiber obtained from cashmere goats, pashmina goats, and some other breeds of goat. It has been used to make yarn, textiles and clothing for hundreds of years. Cashmere is closely associated with the Kashmir shawl, the word "cashmere" deriving from an anglicisation of ''Kashmir'', when the Kashmir shawl reached Europe in the 19th century. Both the soft undercoat and the guard hairs may be used; the softer hair is reserved for textiles, while the coarse guard hair is used for brushes and other non-apparel purposes. A number of countries produce cashmere and have improved processing techniques over the years but China and Mongolia are two of the leading producers as of 2019. Afghanistan is ranked third. Some yarns and clothing marketed as containing cashmere have been found to contain little to no cashmere fiber, so more stringent testing has been requested to make sure items are fairly represented. Poor land management and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the is often defined to be the smallest such distance. Both quantities can be calculated efficiently using rotating calipers. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all ...

Micron (wool)
A micron (micrometre) is the measurement used to express the diameter of wool fibre. Fine wool fibers have a low micron value. Fibre diameter is the most important characteristic of wool in determining its value. Every fleece comprises a very wide range of fibre diameters—for example a typical Merino fleece will contain fibres of as low as 10 microns in diameter, and there could be fibres with diameters exceeding 25 microns, depending on the age and health (or nutrition) of the sheep. What is usually referred to as wool's "micron" is the mean of the fibre diameters or average diameter. This may be measured in a number of different ways. Small samples can be taken from the side or fleece of a sheep and measured using a portable instrument such as an OFDA2000 (Optical Fibre Diameter Analyser); or a mobile instrument system called a Fleecescan. Both these systems have been studied extensively and if used correctly, they should give reasonably reliable results. Pre wool classing m ...

Guard Hair
Guard hair or overhair is the outer layer of hair of most mammals, which overlay the fur. Guard hairs are long and coarse and protect the rest of the pelage (fur) from abrasion and frequently from moisture. They are visible on the surface of the fur and usually lend a characteristic contour and colour pattern. Underneath the contour hair is the short, dense, fine down. There are three types of guard hair: awns, bristles, and spines.G. A. Feldhamer, J. F. Merritt, C. Krajewski, J. L. Rachlow, K. M. Stewart. ''Mammalogy: Adaptation, Diversity, Ecology.

Coat (animal)
Coat is the nature and quality of a mammal's fur. In the animal fancy, coat is an attribute that reflects the quality of a specimen's breeding as well as the level of the animal's care, conditioning, and management. Coat is an integral aspect of the judging at competitions such as a conformation dog show, a cat show, a horse show (especially showmanship classes), or a rabbit show. The pelage of a show animal may be divided into different types of hair, fur or wool with a texture ranging from downy to spiky. In addition, the animal may be single-coated or may have a number of coats, such as an undercoat and a topcoat (also called an ''outer coat'' or, sometimes, ''overcoat''), which is made up of guard hair. The state of the coat is considered an indication of the animal's breeding and health. Animals might have different coat quality for different seasons. Normally, animals with fur or hair body coats may develop a thicker and/or longer winter coat in colder times of the yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Fox
The red fox (''Vulpes vulpes'') is the largest of the true foxes and one of the most widely distributed members of the Order (biology), order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern by the IUCN. Its range has increased alongside human expansion, having been Foxes in Australia, introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included on the list of the List of the world's 100 worst invasive species, "world's 100 worst invasive species". The red fox originated from smaller-sized ancestors from Eurasia during the Middle Villafranchian period, and colonised North America shortly after the Wisconsin glaciation. Among the true foxes, the red fox represents a more progressive form in the direction of Carnivore, carnivory. Apart from its large size, the red fox is disting ...

Vicuña Wool
Vicuña wool refers to the hair of the South American vicuña, an animal of the family of ''camelidae''. The wool has, after shahtoosh, the second smallest fiber diameter of all animal hair and is the most expensive legal wool. Properties The down hair of the vicuña used for the production of vicuña wool is, with an average hair diameter of 11–13.5 microns, one of the finest animal hairs. Only shahtoosh, the hair of the Tibetan antelope, is finer, with an average diameter of 8–13 microns.Carol Ekarius: ''The Fleece & Fiber Sourcebook.'' Storey Publishing, 2011, , pp. 381–382. Among animal textile fibers, besides shahtoosh, only the various silks and byssus have a smaller fiber diameter. The surface structure of the fiber has scales as in sheep wool.Miguel Angel Gardetti: ''Handbook of Sustainable Luxury Textiles and Fashion.'' Springer, 2015, , p. 107. The scale spacing is between 7 and 14 scale rings per 100 microns.Subramanian Senthilkannan Muthu, Miguel Angel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabric
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...
