A mountain paca, also known as a mountain agouti or long-tailed paca, is a rodent found in South and Central America. In Spanish, mountain paca is known as paca de montaña, while in Portuguese it is referred to as pacarana. Other synonyms for this species include Andean paca, highland paca, and Peruvian paca. Although they are similar in appearance to guinea pigs and rabbits, mountain pacas have longer legs and tails, making them adept climbers. Their fur is predominantly brownish-gray, and they have distinctive black and white stripes on their face and neck. The mountain paca is a common target for hunting in some areas, but conservation efforts are underway to protect this species.
