Alpacas and llamas are close relatives within the camelid family, native to the Andes mountains of South America – home to high altitudes and rugged terrain.
Though they share many similarities, these two species have distinct behaviours, appearances, and ecological roles in their native habitats.
What are the similarities between alpacas and llamas?
Both alpacas and llamas belong to the camelid family, which also includes the larger Afro-Asian camels (dromedary and Bactrian) as well as wild South American relatives like vicuñas and guanacos. Camelids are herbivores, adapted to high-altitude environments with long legs, necks, and two-toed feet.
In the wild, their wild relatives guanacos (related to llamas) and vicuñas (related to alpacas) play important roles in Andean ecosystems, grazing on native grasses and shrubs. Though domesticated alpacas and llamas are common today, they retain many of the instincts and social behaviours of their wild cousins.

Both species have complex social structures and communicate with a variety of vocalisations and body language. Both llamas and alpacas have a habit of spitting as a way of warning other members of the same species.
What are the difference between alpacas and llamas?
While llamas and alpacas are often confused, there are several key differences: llamas are generally larger, standing around 120cm at the shoulder and weighing up to 113kg, whereas alpacas are smaller and more delicate, measuring about 90cm tall. Their facial features also vary — llamas have longer, less compact faces and distinctive banana-shaped ears, while alpacas have a shorter, more rounded muzzle.
Temperamentally, llamas tend to be more independent and confident, often used as pack animals in mountainous terrain due to their strength and endurance. Alpacas are typically more timid and herd-oriented, moving in groups and relying on each other for protection.
One of the most noticeable differences between alpacas and llamas is in their coats. Alpacas have a dense, soft fleece prized for its warmth and softness — one of the finest natural fibres after cashmere — while llamas have a coarser double coat better suited to protection from the elements. The range of alpaca colours is also more diverse, from creamy whites to rich browns and blacks, while llamas often display solid shades or spotted patterns.
