Alpaca vs Llama: Size, Fleece, Face and Temperament Compared

Key differences at a glance

The alpaca and the llama are the two domestic camelids of South America, relatives of camels without humps. Both come from the Andes, live in herds, chew the cud, hum and spit, and both are now kept on farms across Europe and North America. They are often confused, especially when young, but they are separate species with different wild ancestors and different jobs.

The table at the top of this page sums up the main differences. The sections below explain each one.

Size: which is bigger?

The llama is clearly the bigger animal. Most adult llamas weigh 130–200 kg (290–440 lb), and large males can be heavier. They stand about 1.0–1.2 m (3.3–4 ft) at the shoulder, and their heads reach about 1.7–1.8 m (5.6–5.9 ft), higher than many adults.

Alpacas weigh 48–90 kg (106–198 lb), most around 55–65 kg (120–145 lb), and stand 81–99 cm (32–39 in) at the shoulder. Next to a llama, an adult alpaca looks compact, with its head usually below the llama’s shoulder line. A large alpaca and a small llama can come close in size, so it pays to check the other features too.

Ears and face

Ears are the most reliable clue. Llamas have long ears that curve inward toward the tips, a shape often called “banana ears”. Alpacas have short, straight, pointed ears, sometimes described as spear-shaped.

The face differs too. A llama has a long, fairly bare face and a longer muzzle, giving it a more horse-like profile. An alpaca has a short, blunt face, often framed by a topknot of fleece, which gives the “teddy bear” look that many people associate with alpacas.

Fleece and fiber

Alpacas have been bred for thousands of years for their fleece. Their coat is dense and fine, with few coarse hairs, and grows in two types: crimpy huacaya and silky, long-locked suri. Adults are shorn once a year and give about 2.3–4.5 kg (5–10 lb) of fiber, prized for soft knitwear. Our article What is alpaca wool? explains the details.

Llamas have a double coat: a soft undercoat mixed with coarser outer guard hairs. Their fleece varies a lot between animals and is less uniform. Llama fiber is used for ropes, rugs and outerwear, and the soft undercoat can be separated for finer yarn, but llamas are rarely kept mainly for fleece.

Uses: pack animal vs fiber animal

For centuries the llama was the Andean beast of burden. A fit llama can carry about 25–30% of its body weight over roughly 8–13 km (5–8 miles) a day in mountain terrain. Llamas also give meat, hides and fiber, and today they are popular for trekking. In North America and Europe, single llamas are often kept with sheep as guard animals, because they tend to confront and chase off dogs and foxes. Our page on what llamas are used for covers this in depth.

Alpacas are too small to carry packs and are kept mainly for fiber, as well as for breeding stock and meat in the Andes. They are wary of foxes and dogs and will raise an alarm, but they are less effective guards than llamas.

Temperament and spitting

Both species are generally calm and gentle. Alpacas are typically shy, nervous of strangers and happiest in the middle of their herd. Llamas are usually bolder, more independent and more willing to approach people, which suits their role as working animals.

Both alpacas and llamas spit, mainly at each other: to settle disputes over food and rank, or when a pregnant female rejects a male. A warning usually comes first, with ears pinned back and the chin lifted. People are rarely the target unless they are caught in the middle. You can learn more in Why do llamas spit?.

Wild ancestors and hybrids

The two species come from different wild camelids. Genetic research published in 2001 confirmed that the alpaca descends mainly from the small, fine-fleeced vicuña and the llama from the larger guanaco. Both wild species still live in South America and are listed as Least Concern by the IUCN.

Because all four South American camelids can interbreed and have fertile young, llamas and alpacas have often been crossed. Their hybrid is called a huarizo. Crossing has been so widespread that many modern alpacas carry some llama ancestry, which helps explain why some animals are hard to classify by looks alone.

Where alpacas and llamas live

Neither species exists in the wild. In South America, both are kept in the high Andes of Peru, Bolivia, Chile and Argentina, but they tend to occupy slightly different niches. Alpacas are concentrated on the wetter high grasslands of southern Peru and Bolivia, often near boggy highland wetlands, at about 3,500–5,000 m (11,500–16,400 ft). Llamas are especially common on the drier Altiplano plateau of western Bolivia and southern Peru, and they cope with sparser, rougher grazing.

Peru has most of the world’s alpacas, while Bolivia has the largest share of llamas. Since the 1980s, both species have been exported to North America, Europe, Australia and New Zealand. Outside South America, alpacas are mostly kept for fleece and breeding, while llamas are popular for trekking, shows and as guards on sheep farms; by the late 2000s the United States and Canada each had substantial herds of both.

Lifespan and care

Llamas usually live 15–25 years, and a few live past 30. Alpacas usually live 15–20 years, with some reaching their mid-twenties. Both are herd animals that should never be kept alone, and both use shared dung piles, which makes them tidy grazers.

In short, if the animal is big, tall and has curved banana ears, it is a llama; if it is small, fluffy-faced and has short, straight ears, it is an alpaca.
