Как пишется по английски морская свинка?

The guinea pig (also commonly called the Cavy after its scientific name, Cavia porcellus) is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not pigs, nor do they come from Guinea. They originated in the Andes, and studies based on biochemistry and hybridization suggest they are domesticated descendants of a closely related species of cavy such as Cavia aperea, C. fulgida or C. tschudii, and therefore do not exist naturally in the wild.
