The Four South American Camelids
One Family — Four Animals
South America has four camelid species: two wild (vicuña and guanaco) and two domesticated (alpaca from vicuña, llama from guanaco). All four are related to Old World camels but diverged from that lineage around 11 million years ago. None of them have humps.

🧶 The Fibre Hierarchy — From Vicuña to Wool
Natural animal fibre quality is measured in microns — the diameter of individual fibres. Finer = softer, warmer per gram, and more expensive. Vicuña: 10–13 microns — the finest in the world; a single vicuña suit costs £10,000–£30,000. Alpaca (baby/royal): 18–22 microns — finer than cashmere, hypoallergenic (no lanolin). Cashmere: 14–19 microns — from Mongolian goats. Alpaca (standard): 22–30 microns — still considerably finer than standard wool. Merino wool: 17–22 microns. Standard sheep wool: 28–35+ microns. The vicuña's extraordinary fibre evolved to keep the animal warm at altitude (3,500–5,000 metres) in the extreme temperature swings of the Andean altiplano. The fibres have a microscopic scale structure that traps air exceptionally efficiently — warmth without weight.
Age Chart
Alpaca Age to Human Years
| Age | Human Equivalent | Life Stage |
|---|---|---|
| 6 months | ~6 yrs | Cria — weaned, growing fast |
| 1 year | ~10 yrs | Juvenile — sub-adult |
| 2 years | ~16 yrs | Young adult — approaching maturity |
| 3 years | ~20 yrs | Adult — first shearing in full production |
| 7 years | ~36 yrs | Prime — peak fibre quality years |
| 12 years | ~52 yrs | Mature — fibre beginning to coarsen |
| 18 years | ~66 yrs | Senior — retirement from breeding |
| 25+ years | ~78 yrs | Elder — exceptional longevity |
Fascinating Facts
Things About South American Camelids That Will Actually Surprise You
🎵 Alpacas Hum
Alpacas communicate primarily through humming — a soft, continuous sound that conveys a range of emotional states. A contented alpaca hums softly; an anxious or curious one hums at a different pitch; a mother hums to her cria (baby). They also produce a distinctive alarm call — a high-pitched bray — when threatened, which alerts the entire herd. Alpacas are remarkably expressive and communicate clearly through ear position, body posture, and tail carriage as well as vocalisations. An ear laid flat back combined with neck arched is a pre-spit warning that an experienced keeper reads immediately.
💦 The Truth About Spitting
Llamas (and alpacas, less commonly) spit — but not at people unless genuinely provoked or poorly managed. The spit is primarily regurgitated stomach content (partially digested grass) rather than saliva — which makes it both more impressive and more unpleasant than people expect. Within the herd, spitting is a communication tool: establishing feeding priority, settling competition for resources, and expressing extreme displeasure. A llama that spits at humans has generally been repeatedly rewarded for the behaviour, often through hand-feeding that establishes disrespect for personal space. Well-handled llamas rarely spit at people.
⛰️ Built for the Altiplano
Vicuñas and their domestic descendants are adapted to survive at altitudes of 3,500–5,000 metres where oxygen is thin and temperature swings between −20°C at night and 20°C during the day. Their blood has an unusually high concentration of red blood cells and their haemoglobin has exceptional oxygen affinity — allowing efficient oxygen transport in thin air. Their padded feet (two toes with tough leathery pads rather than hooves) grip rocky terrain without damaging the fragile Andean grassland (puna). When European horses and cattle were brought to the Andes, they damaged the ecosystem; camelids, evolved for it, do not.
🏛️ Carriers of Civilisation
The llama was the only large domesticated pack animal in pre-Columbian South America — there were no horses, oxen, or donkeys. The entire logistics of Inca civilisation — its vast road network, its armies, its agricultural surpluses, its textiles and pottery — moved on the backs of llamas. A llama can carry approximately 25–30% of its body weight (40–60 kg) over mountainous terrain for sustained distances, does not require grain (grazing suffices), and tolerates altitude that kills horses. The collapse of llama populations after European colonisation — through disease, slaughter, and displacement by cattle and horses — was one of the significant economic blows to indigenous Andean communities.
🦙 The vicuña was hunted nearly to extinction in the 20th century — by 1960 the population had fallen to approximately 6,000 individuals, down from an estimated 2–3 million at the time of European contact. Legal protection from the 1970s onwards, particularly through the Vicuña Convention signed by Peru, Bolivia, Chile, Argentina, and Ecuador, allowed populations to recover to approximately 350,000–400,000 today. It is one of South America's more successful conservation recoveries. The traditional Andean chaku — a community ceremony in which hundreds of people form a human chain to herd vicuñas, shear them, and release them — has been revived in several regions as a legal and sustainable harvest method, with proceeds supporting local communities.

FAQ
Frequently Asked Questions
No — a single alpaca will be profoundly stressed and unhappy. Alpacas are strongly herd animals and require the company of at least one other alpaca (not just any animal — horses, donkeys, or goats are not adequate substitutes for their own species). A solitary alpaca will typically become depressed, stop thriving, and may develop behavioural problems. Most welfare guidelines and many regional regulations require a minimum of two alpacas. The minimum practical herd for a well-functioning social unit is generally considered to be three animals.
Domestic alpacas are shorn once per year, typically in spring before warm weather. A single alpaca produces approximately 2–4 kg of raw fibre per year, of which 1.5–3 kg is usable after skirting (removing the lower-quality edge fibre) and processing. Fibre quality is highest in the first few years of life — "baby alpaca" fibre (not necessarily from young animals, but a grade designation) is the finest and most valuable. Fibre coarsens slightly as the animal ages. Vicuñas, by contrast, can only be shorn every 2–3 years and produce only 200–300g of usable fibre per animal, which is why their fibre is so expensive.
Alpaca fibre is often described as hypoallergenic and is genuinely better tolerated by many people who react to sheep's wool. The primary reason is that wool contains lanolin — a waxy substance produced by sheep's sebaceous glands — to which many people are sensitive or allergic. Alpaca fibre contains no lanolin. Additionally, alpaca fibres have a smoother scale structure than wool fibres, which reduces the prickle sensation that causes discomfort in some people. However, "hypoallergenic" is not an absolute guarantee — a small number of people are allergic to alpaca fibre itself. People with genuine lanolin allergies typically tolerate alpaca well; people with broader fibre sensitivities may still react.
