Hydrochoerus
The genus ''Hydrochoerus'' contains two living and two extinct species of rodents from South America, the Caribbean island of Grenada, California and Panama. Capybaras are the largest living rodents in the world. The genus name is derived from the Greek ὕδωρ (''hýdor'', water) plus χοίρος (''choíros'', pig). Characteristics Capybaras are semiaquatic, found in and near lakes, rivers, swamps, and flooded savanna. Their diets are dominated by grasses. Adults weigh up to . The gestation period is 130–150 days, with two to eight (most commonly four) young born to females. Behavior Capybaras are highly social, living in groups of up to 100 and communicating through a variety of vocalizations.Rowe and Honeycutt, 2002 Breeding is polygynous, with males forming harems. Phylogeny and taxonomy Molecular results have consistently suggested ''Hydrochoerus'' is most closely related to ''Kerodon'' (the rock cavies), and the two evolved from within the Caviidae. This ...

Capybara
The capybaraAlso called capivara (in Brazil), capiguara (in Bolivia), chigüire, chigüiro, or fercho (in Colombia and Venezuela), carpincho (in Argentina, Paraguay and Uruguay) and ronsoco (in Peru). or greater capybara (''Hydrochoerus hydrochaeris'') is a giant cavy rodent native to South America. It is the largest living rodent and a member of the genus '' Hydrochoerus''. The only other extant member is the lesser capybara (''Hydrochoerus isthmius''). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the nutria. The capybara inhabits savannas and dense forests, and lives near bodies of water. It is a highly social species and can be found in groups as large as 100 individuals, but usually live in groups of 10–20 individuals. The capybara is hunted for its meat and hide and also for grease from its thick fatty skin. It is not considered a threatened species. Etymology Its common name is deriv ...

Hydrochoerus Hesperotiganites
''Hydrochoerus hesperotiganites'' is an extinct species of capybara that lived in San Diego County, California, during the Rancholabrean stage of the Pleistocene (between 130,000 and 80,000 years ago). It is currently the only known capybara of the genus ''Hydrochoerus'' found in North America. It was closely related to the modern Greater and Lesser Capybara. History and naming The holotype specimen of ''H. hesperotiganites'' was collected by the San Diego Society of Natural History by Bradford O. Riney during mitigation monitoring at the Town Center North shopping center, City of Oceanside, California. The fossil was recovered from the lower of two stratigraphic units, consisting of sandstone, mudstone and siltstone dating to the Pleistocene. The sediments more specifically most likely date to the Rancholabrean based on typical mammal fauna of that age and the presence of ''Bison latifrons'' from possibly correlative strata upriver from the locality. The species name "hesp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydrochoerus Holmesi
''Neochoerus aesopi'' was a relatively large rodent species native to North America until their extinction about 12,000 years ago, being closely related to modern capybaras (genus ''Hydrochoerus''). It was part of the subfamily ''Hydrochoerinae''. Fossils of it have been found in U.S. states such as Florida and South Carolina. The species was originally outlined in 1853, it weighed about 80 kg similar in size to the modern day capybara. It has been synonymized with ''Hydrochoerus holmesi'' and several other formerly recognized extinct taxa. Identification of these types of rodent fossils is an inexact science, and lines between various classifications are often questionable. Unlike extant capybaras, ''N. aesopi'' lived in North America, where its ancestors had migrated from South America during the Great American Interchange.

Hydrochoerus Gaylordi
''Hydrochoerus gaylordi'' (named after American political consultant Joseph Gaylord) is an extinct species of capybara that lived in Grenada during the Late Pliocene to Early Pleistocene. This species was found in 1991 by Ronald Singer and his colleagues based on a maxilla bearing 3 molars, but it was not named until 2000. It may be invalid and a synonym of the extant greater capybara. Discovery and naming Fossils of ''Hydrochoerus gaylordi'' were first collected in 1991 by American paleontologist Robert Singer and party from a cliff face on the property of the 12° North Hotel in Lance aux Épines, southern Grenada, where fossils of megalonychid sloths were found earlier by the co-owner of the hotel, Joseph Gaylord, in 1982. The ''H. gaylordi'' fossils consisted only of a partial maxilla preserving M1-M3 that was donated to the American Museum of Natural History, where it is deposited under specimen number AMNH-VP 132713. The geologic dating of the fossils is uncertain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrochoerinae
Hydrochoerinae is a subfamily of Caviidae, consisting of two living genera, '' Hydrochoerus'', the capybaras, and ''Kerodon'', the rock cavies. In addition, a number of extinct genera related to capybaras should also be placed in this subfamily. The taxonomy of Hydrochoerinae is confused because, until 2005, living capybaras and their extinct relatives were placed in their own family, Hydrochoeridae.McKenna, Malcolm C., and Bell, Susan K. 1997. ''Classification of Mammals Above the Species Level.'' Columbia University Press, New York, 631 pp. Recent molecular phylogenetic studies recognize a close relationship between ''Hydrochoerus'' and ''Kerodon'', supporting placement of both genera in a subfamily of Caviidae. Paleontological classifications have yet to incorporate this new taxonomy, and continue to use Hydrochoeridae for all capybaras, while using Hydrochoerinae for the living genus and its closest fossil relatives such as ''Neochoerus ''Neochoerus'' ("new hog") is a ...

Caviidae
Caviidae, the cavy family, is composed of rodents native to South America and includes the domestic guinea pig, wild cavies, and the largest living rodent, the capybara. They are found across South America in open areas from moist savanna to thorn forests or scrub desert. This family of rodents has fewer members than most other rodent families, with 19 species in 6 genera in 3 subfamilies. Characteristics With the exception of the maras, which have a more rabbit-like appearance, caviids have short, heavy bodies and large heads. Most have no visible tails. They range in size from the smaller cavies at 22 cm in body length, and 300 grams in weight, up to the capybara, the largest of all rodents at 106 to 134 cm in length, and body weights of 35 to 66 kilograms. Even larger forms existed in the Pliocene, such as '' Phugatherium'', which was about the size of a tapir. They are herbivores, eating tough grasses or softer leaves, depending on species.

Kerodon
The genus ''Kerodon'' (vernacular name Mocos; Rock Cavies) contains two species of South American rock cavies, related to capybaras and guinea pigs. They are found in semiarid regions of northeast Brazil known as the Caatinga. This area has a rocky terrain with large granite boulders that contain rifts and hollows where ''Kerodon'' spp. primarily live. Characteristics They are hystricomorph rodents, medium-sized, with rabbit-like bodies, a squirrel-like face, and heavily padded feet. Their nails are blunt on all digits except a small grooming claw on the outermost digit of the foot. Fully grown adults weigh around 1000 g or 31-35 oz, and range in length from 200 to 400 mm or 7.5 to 16 in. They forage for mostly leaves, grasses, seeds, and tree bark. They breed year round, usually having one to three litters per year and one to three young per pregnancy. Gestation last around 76 days and the young are weaned from the mother within 33 days. They reach sexual maturity at 133 days. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gestation Period
In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. It begins when a fertilized zygote implants in the female's uterus, and ends once it leaves the uterus. Fertilization and implantation During copulation, the male inseminates the female. The spermatozoon fertilizes an ovum or various ova in the uterus or fallopian tubes, and this results in one or multiple zygotes. Sometimes, a zygote can be created by humans outside of the animal's body in the artificial process of in-vitro fertilization. After fertilization, the newly formed zygote then begins to divide through mitosis, forming an embryo, which implants in the female's endometrium. At this time, the embryo usually consists of 50 cells. Development After implantation A blastocele is a small cavity on the center of the embryo, and the developing embryonary cells will grow around it. Then, a flat layer cell f ...
