Brazilian Guinea Pig
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 272 mm (11 in) and a weight of 637 grams (22.5 oz). 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 400 and 3,000 metres (1,300 and 9,800 ft) above sea level.
