Vicugna pacos, commonly known as alpacas, are popular domesticated South American camelids that resemble llamas. The word "alpaca" is derived from the Aymara language spoken by indigenous peoples in the Andes region of South America. There are several synonyms used to refer to vicugna pacos, including alpaco, paca, pacu, and cama (which is the Quechua word for alpaca). Alpacas are known for their soft and durable wool, which has been prized by humans for thousands of years. They are also a source of food and used in traditional ceremonies by Andean communities. Vicugna pacos are fascinating animals that have played an important role in the culture and economy of South America.
