Cavia
''Cavia'' is a genus in the subfamily Caviinae that contains the rodents commonly known as the guinea pigs or cavies. The best-known species in this genus is the domestic guinea pig, ''Cavia porcellus'', a meat animal in South America and a common household pet outside that continent. Characteristics General characteristics The true guinea pigs are medium-sized rodents. They reach a head-body length of 20 to 35 centimeters (8 to 14 inches) and a weight of 500 to a maximum of 1,000 grams. The largest species of the genus is the greater guinea pig (''Cavia magna''). The species are very similar in habit and appearance, the long and relatively rough fur is usually grayish or brown to reddish-brown in color. The coloring can be variable, especially in species with a large distribution area and several subspecies. The head is relatively large in relation to the body, the eyes are large and the ears are small. The legs are short and strong, the front feet have four toes and the h ...

Cavia Porcellus
The guinea pig or domestic guinea pig (''Cavia porcellus''), also known as the cavy or domestic cavy ( ), is a species of rodent belonging to the genus ''Cavia'', family Caviidae. Animal fancy, Breeders tend to use the name "cavy" for the animal, but "guinea pig" is more commonly used in scientific and laboratory contexts. Despite their name, guinea pigs are not native to Guinea (region), Guinea, nor are they closely related to suidae, pigs. Instead, they originated in the Andes region of South America, where wild guinea pigs can still be found today. Studies based on biochemistry and DNA Hybrid (biology), hybridization suggest they are domestication, domesticated animals that do not exist naturally in the wild, but are descendants of a closely related cavy species such as ''Montane guinea pig, C. tschudii''. Originally, they were domesticated as livestock (source of meat) in the Andean region and are still consumed in some parts of the world. In Western society, the guin ...

Cavia Intermedia
Santa Catarina's guinea pig (''Cavia intermedia'') or Moleques do Sul cavy is a rare guinea pig species of southeastern South America. Distribution The small mammal is endemic to the , located in the state of Santa Catarina in southern Brazil. The archipelago formed about 8,000 years ago, having a total of three islands with a surface area of only . ''Cavia intermedia'' is phylogenetically comparable, and said to be a common ancestor of the species '' Cavia magna'', who also inhabited the island. The guinea pig's geographical distribution of only is one of the world's smallest for a mammal. The region is a part of Serra do Tabuleiro State Park where restrictions and protection of the species are not enforced. When population densities were estimated, two techniques were used, one was determined using trapping grids, which is usually placed in optimum habitat, which would be only 0.77ha, which are their feeding grounds. This first estimate is 28-44cavies/ha, which is believed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Guinea Pig
''Cavia magna'', commonly known as the greater guinea pig, is a species of rodent in the family Caviidae, native to South America. It is found primarily in the coastal regions of southern Brazil and Uruguay, inhabiting grasslands, marshes, and other wetland environments. ''Cavia magna'' is closely related to the domesticated guinea pig (''Cavia porcellus'') but is distinct in its larger size and semi-aquatic habitat preferences. This species exhibits adaptations to its wetland habitats, including a preference for dense vegetation near water. Greater guinea pigs are herbivorous, feeding on grasses, sedges, and other vegetation, and play a role in maintaining the ecological balance of their native habitats. Unlike their domesticated relatives, they are not kept as pets and are primarily studied in the context of their ecological and evolutionary significance.

Cavia Tschudii
The montane guinea pig (''Cavia tschudii'') is a species of caviid rodent found in the Andes in South America. The montane guinea pig is the likely main ancestor of ''Cavia porcellus'', the domestic guinea pig or domestic cavy, which appears to be a hybrid that includes lesser genetic contributions from other ''Cavia'' species. Taxonomy Peruvian wild guinea pigs were first described by E. T. Bennett in 1835, who termed them ''Cavia cutleri''. J. J. Tschudi, in an 1845 publication, used the term ''Cavia cutleri'' to refer to what are now considered two separate species: The first, Bennett's ''Cavia cutleri'', which was later identified (by O. Thomas in 1917) as probably a differently-pigmented version of ''Cavia porcellus'', and the second, a wild Peruvian guinea pig that was clearly different from the animal Bennett described. In 1867, L. Fitzinger renamed the clearly wild guinea pig ''Cavia tschudii''. Description The montane guinea pig is a medium-sized species, growing t ...

Caviinae
Caviinae is a subfamily uniting all living members of the family Caviidae with the exception of the maras, capybaras, and '' Kerodon''. The subfamily traditionally contained the guinea pig or cavy-like forms along with the cursorially adapted (running) ''Kerodon''. Molecular results suggest the Caviinae as so defined would be paraphyletic and ''Kerodon'' is more closely related to maras and capybaras than to other caviines.Rowe, D. L. and R. L. Honeycutt. 2002. Phylogenetic relationships, ecological correlates, and molecular evolution within the Cavioidea (Mammalia, Rodentia). Molecular Biology and Evolution, 19:263-277. This led Woods and Kilpatrick (2005) to unite ''Kerodon'' and capybaras into the subfamily Hydrochoerinae within the Caviidae. These studies also suggest '' Microcavia'' and ''Cavia'' are more closely related to one another than either is to '' Galea''.

Cavia Guianae
''Cavia guianae'' is a guinea pig species from South America. It is found in southern Venezuela, Guyana, and portions of northern Brazil Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is the world's List of countries and dependencies by area, fifth-largest country by area and the List of countries and dependencies by population .... Some biologists believe it to be a feral offshoot of the domestic guinea pig, ''Cavia porcellus''; others subsume it under the wild cavy, '' Cavia aperea''. Molecular data collected show there is little genetic differentiation in ''C.a. guianae'' known to be a lowland locality in comparison to ''C. anolaimae'' which are predominantly highland populations.

Cavia Anolaimae
''Cavia anolaimae'' is a guinea pig species from South America. It is found in Colombia near Bogotá. It is believed to be a feral offshoot of the domestic guinea pig, ''Cavia porcellus'', and is often treated as a synonym of ''C. porcellus'', but Zúñiga et al.

Cavia Aperea
The Brazilian guinea pig (''Cavia aperea'') (''preá'' in Portuguese) is a wild guinea pig species found in Argentina, Brazil, Bolivia, Colombia, Ecuador, Guyana, Paraguay, Uruguay and Venezuela. ''Cavia aperea'' has been successfully mated to the domestic guinea pig, ''Cavia porcellus'', though many females become infertile in successive generations. Brazilian guinea pigs are mainly diurnal animals and are narrower and longer than domesticated guinea pigs. Description This is a medium-sized guinea pig with an adult length of about and a weight of . The tail, at around 2.4 mm, is almost non-existent. The dorsal fur is dark olive-brown mixed with brown and black, and the underparts are a pale grey or yellowish-grey. Its karyotype has 2n = 64 and a reportedly variable FN of 116 or 128 for ''C. a. aperea'' and 128 for ''C. a. pamparum''. Distribution The Brazilian guinea pig has a wide distribution in South America at altitudes between above sea level. Its range extends ...

Galea (genus)
''Galea'' is a genus of South American rodents of the family Caviidae. 5-6 extant species are known, found in Argentina, Bolivia, Chile, Peru and Brazil. They are: * Southern highland yellow-toothed cavy ('' G. comes'') * Brazilian yellow-toothed cavy (''G. flavidens'') * Lowland yellow-toothed cavy ('' G. leucoblephara'') * Common yellow-toothed cavy (''G. musteloides'') ** Muenster yellow-toothed cavy (''G. m. monasteriensis'' or ''G. monasteriensis''?) * Spix's yellow-toothed cavy (''G. spixii'') ''Galea'' has until recently been considered to have only three species; the Muenster yellow-toothed cavy was only described in 2004. ''G. flavidens'' is monotypic and ''G. musteloides'' and ''G. spixii'' are polytypic. ''Galea'' is in the family Caviidae and its members are described as cavies; they have sometimes also been called "guinea pigs". Cavies are widespread throughout South America.
