📍 Machu Picchu, Peru
Llama (Lama glama)
As the Inca Empire’s primary pack animal, llamas hauled goods across a road network that stretched thousands of miles through the Andes, sustaining an empire that never used the wheel.
A resident population lives year-round at the citadel, maintained by Peru’s Ministry of Culture as both a conservation nod and a living link to the site’s history.
