Miniature Lop
Miniature Lop is a breed of domestic rabbit recognised by the British Rabbit Council (BRC). Confusion arises because, in the UK, the Miniature Lop is often commonly called (for short) the ''Mini Lop''. It is, however, a different breed from the ''Mini Lop'' that is recognized by the American Rabbit Breeders Association (ARBA). The BRC-recognized Miniature Lop is most similar to the ARBA-recognized Holland Lop. The Miniature Lop is also similar to several other Dwarf rabbit, small rabbit breeds. History The Miniature Lop in Britain is a relatively new rabbit breed, and it is descended from the first dwarf lops that were developed in the Netherlands during the 1970s. These are now called, in the US, the ''Holland Lop'', but in the Netherlands, they are known as the ''Miniature Lop''. A Dutch rabbit breeder, Adriann de Cock, is generally credited with developing in late 1949 the dwarf lop breeds, by crossing the French Lop (one of the largest of the lop breeds) with the tiny Neth ...

Agouti Gene
Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. It is responsible for the distribution of melanin pigment in mammals. Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment). This interaction is responsible for making distinct light and dark bands in the hairs of animals such as the agouti, which the gene is named after. In other species such as horses, agouti signalling is responsible for determining which parts of the body will be red or black. Mice with wildtype agouti will be grey, with each hair being partly yellow and partly black. Loss of function mutations in mice and other species cause black fur coloration, while mutations causing expression throughout the whole body in mice cause yellow fur and obesity. The agouti-signaling protein (ASIP) is a competitive antagonist with alpha-Melanocyte-stimulating hormon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lop Rabbit
Lop rabbit or lop-eared rabbit refers to any rabbit with ears that droop, as opposed to being carried erect. A number of rabbit breeds (listed below) are characterized by such lop ears. Abnormalities in the skull of a half-lop rabbit were studied by Charles Darwin in 1868. Ear carriage The defining feature of the lop rabbit is its ear carriage. Unlike the erect ear of the majority of domestic rabbit breeds, lop breeds have ears loosely drooping, with the opening of the ear facing the skull. Due to the slightly-raised cartilaginous ear base, the head of many lop rabbits (with the exception of English Lops) has a small bulge, referred to as the ''crown''. The head of a typical lop rabbit is said to resemble that of a male sheep in profile, thus the German term for a lop rabbit ''(Widder,'' meaning ''Aries he ram'', the French term ''(bélier,'' meaning ''ram'') and the Italian term (''ariete'', from Latin ''aries''). A rabbit's ear, with its blood vessels close to the surface, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rabbit Breeds
As of 2017, there were at least 305 breeds of domestic rabbit in 70 countries around the world. A rabbit breed is a distinct variety created through selective breeding (or occasionally natural selection) for specific characteristics, including size, fur (length, quality, or color), feed conversion ratio, climate adaptability, or temperament. Groups such as the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC) coordinate and standardize the desired qualities of their recognized breeds, through promotion and exhibition. Each rabbit breed is considered to benefit when a reputable breeder strives to emulate the purpose for the breed, often defined by the individual breed standard by which it may be judged. The global diversity of breeds reflects the breadth of the rabbit's unique qualities. Listed below are 191 of the world's modern-day rabbit breeds.

Opal
Opal is a hydrated amorphous form of silica (SiO2·''n''H2O); its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Due to its amorphous property, it is classified as a mineraloid, unlike crystalline forms of silica, which are considered minerals. It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt. The name ''opal'' is believed to be derived from the Sanskrit word (), which means 'jewel', and later the Greek derivative (), which means 'to see a change in color'. There are two broad classes of opal: precious and common. Precious opal displays play-of-color ( iridescence); common opal does not. Play-of-color is defined as "a pseudo chromatic optical effect resulting in flashes of colored light from certain minerals, as they are turned in white light." The internal structure of precious opal causes it to di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fawn
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as red dee ...

Chinchilla
Chinchillas are either of two species (''Chinchilla chinchilla'' and ''Chinchilla lanigera'') of crepuscular rodents of the parvorder Caviomorpha. They are slightly larger and more robust than ground squirrels, and are native to the Andes mountains in South America. They live in colonies called "herds" at high elevations up to . Historically, chinchillas lived in an area that included parts of Bolivia, Peru, Argentina, and Chile, but today, colonies in the wild are known only in Chile. Along with their relatives, viscachas, they make up the family Chinchillidae. They are also related to the chinchilla rat. The chinchilla has the densest fur of all mammals that live on land. In the water, the sea otter has a denser coat. The chinchilla is named after the Chincha people of the Andes, who once wore its dense, velvet-like fur. By the end of the 19th century, chinchillas had become quite rare after being hunted for their ultra-soft fur. Most chinchillas currently used by the fur ind ...

Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netherland Dwarf
The Netherland Dwarf is a breed of domestic rabbit that originated in the Netherlands. Weighing , the Netherland Dwarf is one of the smallest rabbit breeds. Its popularity as a pet or show rabbit may stem from its neotenic appearance. The Netherland Dwarf is recognised by both the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC). The Netherland Dwarf is often confused with the Polish breed of rabbit, but the latter has longer ears, a non-brachycephalic head and less cobbiness. History The Netherland Dwarf breed was first produced in the Netherlands in the early 20th century. Small Polish rabbits were bred with smaller wild rabbits; after several generations the resulting animal was a very small domestic rabbit available in a wide variety of colours and patterns. Netherland Dwarfs were first imported into the United Kingdom in 1948. In the 1960s and 1970s the United States imported its first Netherland Dwarf rabbits. The breed was accepted b ...

Domestic Rabbit
A domestic or domesticated rabbit (''Oryctolagus cuniculus domesticus'')—more commonly known as a pet rabbit, bunny, bun, or bunny rabbit—is a subspecies of European rabbit, a member of the lagomorph family. A male rabbit is known as a ''buck,'' a female is a ''doe,'' and a young rabbit is a ''kit'', or ''kitten''. Rabbits were first used for their food and fur by the Romans, and have been kept as pets in Western nations since the 19th century. Rabbits can be housed in exercise pens, but free roaming without any boundaries in a rabbit-proofed space has become popularized on social media in recent years. Beginning in the 1980s, the idea of the domestic rabbit as a house companion, a so-called ''house rabbit'' similar to a house cat, was promoted. Rabbits can be litter box-trained and taught to come when called, but they require exercise and can damage a house that has not been "rabbit proofed" based on their innate need to chew.

French Lop
The French Lop is a breed of domestic rabbit developed in France in the 19th century from the selective breeding of English Lop and Flemish Giant stock. The French Lop resembles the English Lop, but the French Lop is heavier in stature and does not have the exaggerated ear length of the English Lop. Weighing approximately 4.98 kg to 5.21 kg, it has an average lifespan of five to seven years. The French Lop is currently recognized by the American Rabbit Breeders Association (ARBA) and by the British Rabbit Council (BRC). History The French Lop was first bred as a meat rabbit, beginning around 1850 in France. It is believed to have been produced by crossing two existing breeds, the English Lop and the Giant Papillon ("géant papillon français" or "Butterfly Rabbit of France"). The new breed became popular in neighbouring countries including the Netherlands, from which ten specimens were exported in 1933 to the UK for exhibition there. By the 1960s, the French Lop had become a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
