The Pacarana (Dinomys branickii) is a rare and slow-moving hystricognath rodent indigenous to South America. Native peoples of the region call it the pacarana (false paca) because it is superficially similar to the paca, a different rodent which is not in the same family. The pacarana has a chunky body and is large for a rodent, weighing up to 15 kg (33 lb) and measuring up to 79 cm (31 in) in length, not including the thick, furry tail.
