The Brazilian guinea pig (Cavia aperea) (preá in Portuguese) is a guinea pig species found in Argentina, Brazil, Colombia, Ecuador, Paraguay, and Uruguay.

C. aperea has been successfully mated to the domestic guinea pig, Cavia porcellus, though many females become infertile in successive generations.[2] Brazilian guinea pigs are nocturnal animals. They are narrower and longer than domesticated guinea pigs.
