CAVY , a name commonly applied to several See also:

South See also:American rodent animals included in the See also:family Caviidae (see See also:RODENTIA), but perhaps properly applicable only to those belonging. to the typical genus Ca ia, of which the most See also:familiar representative is the domesticated See also:guinea-See also:pig. Cavies in See also:general, the more typical representatives of the Caviidae, are rodents with hoof-like nails, four front and three See also:hind toes, imperfect See also:collar-bones, and the cheek-See also:teeth divided by folds of See also:enamel into transverse plates. The tail is See also:short or rudimentary, the incisors are short, and the See also:outer See also:surface of the See also:lower See also:jaw is marked by a distinct See also:ridge. True cavies, or conies (Cavia), are best known by the guinea-pig, a domesticated and parti-coloured See also:race derived from one of the See also:wild See also:species, all of which are uniformly coloured. They are comparatively small and stoutly built animals, with short, rounded ears and no tail. In habits they are partly diurnal; and live either in burrows among the crevices of rocks, beneath the leaves of aquatic See also:plants in marshy districts, or underneath the floors of outbuildings. Their cries are faint squeaks and grunts. They feed upon nearly all See also:vegetable substances, but drink little. Generally they See also:associate in small See also:societies, and seldom wander far from See also:home. Although the guinea-pig is a fertile breeder, the wild species only produce one or two See also:young at a See also:birth, and this but once in a See also:year. The young come into the See also:world in a highly See also:developed See also:condition, being able to feed them-selves the See also:day following their birth. Cavies are widely distributed in South See also:America, and are represented by several species.

Among them may be mentioned the aperea or restless cavy (C. porcellus or C. aperea) of See also:

Brazil; the Bolivian C. boliviensis, found at See also:great elevations in the See also:Andes; the Brazilian See also:rock-cavy (C. rupestris), characterized by its short See also:blunt claws; and the Peruvian C. cutleri. The latter was tamed by the Incas, and is the ancestor of the guinea-pig. As to the origin of that name, some writers consider it a corruption of See also:Guiana-pig, but it is more probable that the word " Guinea " merely signifies See also:foreign. The guinea-pig is a singularly inoffensive and defenceless creature, of a restless disposition, and wanting in that intelligence which usually characterizes domestic pets, although said to show some discrimination. It is of no particular service to See also:man, neither its flesh nor its See also:fur being generally put to use, while the statement that its presence is sufficient to drive off rats and mice appears to be without See also:foundation. It is exceedingly prolific, beginning to breed at the See also:age of two months; the number of young varying, according to the age of the See also:parent, from four to twelve. It has been calculated that a single pair of guinea-pigs may prove the parent stock of a thousand individuals in a single year. A very different See also:animal is the Patagonian cavy, or See also:mara (Dolichotis pataclsonica), the typical representative of a genus characterized by See also:long limbs, comparatively large ears, and a short tail: The animal is about the See also:size of a See also:hare, to which it approximates in See also:form and habits. It is most abundant in the open districts of See also:Patagonia, but also ranges on to the See also:Argentina See also:Pampas, where it is now scarce. Although occasionally seen in large flocks, the mara is more commonly found in small parties or in pairs, the parties commonly moving in single See also:file. It has a See also:peculiar See also:kind of hopping gait; and is mainly diurnal, in accordance with which See also:habit its eyes are protected by lashes. It lives in a burrow, generally excavated by itself; but when pursued, seeks safety in See also:flight, rather than by a See also:retreat to, its hole.

From two to five young are produced twice a year. A much smaller species, D. salinicola, without the characteristic See also:

black See also:band above the tail, inhabits the See also:salt-plains of Argentina. Maras have been introduced into several See also:British parks. Fossil *pecies of Dolichotis occur in the caverns of Brazil, and also the superficial deposits of Argentina. (R.
