Which of the South American camelids is physically the smallest?
Answer
The vicuna
Among the members of the South American camelid family, the vicuna is the smallest. While other members like the llama can be quite large, the vicuna is built for agility and high-altitude endurance. An adult vicuna typically stands between 0.75 and 1 meter tall at the shoulder and weighs between 35 and 65 kilograms, reflecting its evolutionary adaptation to the harsh, thin-aired environment of the high Andes.
