pacarana

n. large and rare rodent that moves slowly and has a thick furry tail and dark brown/ black fur with white stripes running lengthwise along the back and other white spots (native to South America), rodent which is the largest species of mouse

The pacarana (Dinomys branickii) is a rare and slow-moving South American rodent found only in tropical forests of the western Amazon River basin and adjacent foothills of the Andes Mountains from northwestern Venezuela and Colombia to western Bolivia.Also known as Count Branicki's terrible mouse, it is known as the "pacarama" ("false paca") by native Indians due to its superficial similarity to an unrelated rodent, the paca. It is a hystricognath rodent, and the sole member of the family Dinomyidae in the infraorder Caviomorpha; initially, it was placed with true mice. Some evidence places the pacarana as closely related to the prehistoric giant rodents that ruled South America millions of years ago, such as Phoberomys pattersoni.
