SPECIES Cavia porcellus
Author: | Linnaeus, 1758. | Citation: | Syst. Nat., 10th ed., 1: 59. | Common Name: | Domesticated Guinea Pig | Type Locality: | Brazil, Pernambuco (questionable). | Distribution: | Domesticated worldwide; possibly feral in N South America. | Status: | IUCN – Lower Risk (lc). | Comments: | Husson (1978:451) reserved the use of porcellus to denote domesticated guinea pigs, which are probably derived from tschudii (Corbet and Hill, 1991:201), but also see Hückinghaus (1961:96), who regarded porcellus as a synonym of aperea. This species may be a domesticated animal with no established wild populations, K. F. Koopman (pers. comm.) believed that N South American populations may be feral domesticated guinea pigs; but see comments under aperea. Cavia aperea can be differentiated from porcellus by the presence of the processus cupularis (da Silva Neto, 2000). Karyotype has 2n=64 and FN=128 (George and Weir, 1974). |
