Abrocoma Bennettii
Bennett's chinchilla rat (''Abrocoma bennettii'') is a species of chinchilla rat in the family Abrocomidae. It is found only in Chile where its habitat is Mediterranean-type scrub on the western side of the Andes. The IUCN has assessed its conservation status as being of "least concern". Description Bennett's chinchilla rat is the largest species in the genus, with an average head-and-body length of and a tail about 80% of this. As with other members of the genus, the fur is long, dense and soft, and the ears prominent and rounded. The feet are broad but short, with four toes on the front feet and five on the hind; the small, nail-like claws are hidden by tufts of stiff bristles. The dorsal pelage is dark brown tinged with grey, slightly paler on the flanks, and the hairs on the underparts have dark grey bases and pale grey tips; this gives them a frosted appearance and distinguishes this species from other members of the genus which have pale underparts. The tail is well-hair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Robert Waterhouse
George Robert Waterhouse (6 March 1810 – 21 January 1888) was an English naturalist. He was a keeper at the department of geology and later curator of the Zoological Society of London's museum. Early life George was born in Somers Town to James Edward Waterhouse and Mary Newman. His father was a solicitor's clerk and an amateur entomologist. He was the brother of Frederick George Waterhouse, who also became a zoologist. George went to school at Koekelberg, near Brussels. He returned to England in 1824 and worked as an apprentice to an architect. Part of the work was in designing the garden of Charles Knight in the Vale of Health, Hampstead and the ornamentation for St. Dunstan's Church. Natural history George became interested in entomology through his father and he founded the Entomological Society of London along with Frederick William Hope in 1833 with himself as honorary curator. He became its president in 1849–50. He wrote articles for Knight's ''Penny Cyclopædia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinchilla Rat
Chinchilla rats or ''chinchillones'' are members of the family Abrocomidae. This family has few members compared to most rodent families, with only nine known living species. They resemble chinchillas in appearance, with a similar soft fur and silvery-grey color, but have a body structure more like a short-tailed rat. They are social, tunnel-dwelling animals, and live in the Andes Mountains of South America. They are probably herbivorous, although this is not clear. They can be described as medium-sized. Stiff hairs project over the three middle digits of the rear feet. Their massive skulls narrow in the facial areas. Some molecular work suggests that, despite their appearance, they may be more closely related to octodontoids such as degus, nutria, and tuco-tucos than they are to chinchillas and viscachas. Etymology The family name is derived from the Ancient Greek word ἁβροκόμης (''habrokomēs'', "with delicate hair"). The word ἁβρός (habros) means "delicate ...

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalu ...

Common Degu
The common degu (''Octodon degus''; ), or, historically, the degu, is a small hystricomorpha rodent endemic to the Chilean matorral ecoregion of central Chile. The name ''degu'' on its own indicates either the entire genus '' Octodon'' or, more commonly, just the common degu. Common degus belong to the parvorder Caviomorpha of the infraorder Hystricognathi, along with the chinchilla and guinea pig. The word ''degu'' comes from the indigenous language of Chile, Mapudungun, and the word ''dewü'', meaning 'mouse' or 'rat'. The animal may be kept as a pocket pet, though there are prohibitions on their ownership in some territories. As a pet, the animal is larger than a golden hamster but smaller than a fancy rat. Description The common degu is a small animal with a body length of and a weight of . It has yellow-brown fur above and creamy-yellow below, with yellow around the eyes and a paler band around the neck. It has a long, thin tail with a tufted, black tip, dark ...

Chilean Rock Rat
The Chilean rock rat (''Aconaemys fuscus'') is a species of rodent in the family Octodontidae. It is found in the high Andes of Argentina and Chile. Description The Chilean rock rat is a short-tailed rodent. Rock rats in the genus '' Aconaemys'' are similar to those in the genus '' Ctenomys'' but not so specialised for life underground. The ears are rather larger, the claws on the front feet which are used for digging are smaller, and the edging of hairs on the hind feet, used for shifting loose soil, is reduced in size. The upper parts of the Chilean rock rat are dark brown, with the underparts ranging from reddish brown to white. Sample specimens described in 1966 and 1984, from two different locations, had a head-and-body length ranging from to , with the tail adding another – to the animal's total length. Its karyotype has 2n = 56 and FN = 108. Distribution and habitat This species is endemic to parts of Argentina and Chile in the high Andes in South America. Its ran ...

Long-tailed Chinchilla
The long-tailed chinchilla (''Chinchilla lanigera''), also called the Chilean, coastal, common, or lesser chinchilla, is one of two species of rodent from the genus ''Chinchilla'': the other species being '' C. chinchilla''. Both species are endangered in the wild after historically being hunted for their soft hair coats. Domestic breeds of chinchilla are believed to descend from specimens of ''C. lanigera''. Domestic chinchillas come in three types: ''la plata, costina'', and ''raton''. Historically, Chilean chinchillas were reported from Talca (35°30’S), Chile, north to Peru, and also eastward, from Chilean coastal hills, throughout low mountains. No fossils of the Chilean chinchilla are known to have been found, and by the mid-19th century, Chilean chinchillas were not found south of the Choapa River in central Chile. Wild populations of Chilean chinchillas, as of 1996, occurred in Aucó (31°38’S, 71°06’W), near Illapel, IV Región, Chile, in Reserva Nacional Las Chi ...

Mammals Of Chile
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...
