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. Wikipedia →
