Alpaca: Characteristics, Diet, Facts & More [Fact Sheet]

With their long, graceful necks and curious, large eyes, alpacas have a unique charm that irresistibly attracts animal lovers around the globe.

Native to the high Andes of South America, these soft-footed creatures have been bred for their valuable wool for thousands of years, and have made a significant impact on textile industries worldwide.

Agile and hardy, alpacas have adapted to harsh environments that are often too challenging for other domesticated animals. This article delves into the fascinating world of the alpaca, exploring their behavior, diet, habitats, and much more.

Species and Subspecies

There is only one recognized species of alpaca, Vicugna pacos. However, alpacas are commonly divided into two types or breeds based on their fiber characteristics: Huacaya and Suri.

Huacaya alpacas, the most common type, make up about 90% of all alpacas and are distinguished by their fluffy, crimped wool that gives them a teddy bear-like appearance.

On the other hand, Suri alpacas are rarer, making up the remaining 10%. They have long, lustrous, and curly fibers that hang down in beautiful dreadlock-style locks.

Three alpacas


Alpacas are small, camelid animals standing at an average shoulder height of 34-36 inches (85-92 cm). Their average weight ranges from 121 to 143 lbs (55-65 kg).

They are well-known for their dense, soft wool that comes in a range of 22 natural colors, from a true, non-fading black to brilliant white and various shades of fawn, brown, and gray in between.

In terms of sexual dimorphism, male and female alpacas are relatively similar in size, but males often have slightly larger and more pronounced incisor and canine teeth (commonly known as “fighting teeth”) that can be used during dominance disputes.

Habitat and Distribution

Alpacas are native to the Andean mountain range of South America, particularly Peru, Bolivia, Ecuador, and northern Chile, where they inhabit high altitudes of up to 14,500 feet (4,400 meters). The harsh, high-altitude environments of the Andes, with poor vegetation, cold temperatures, and thin air, have shaped the alpacas into the hardy, adaptable animals we know today.

Their exceptional wool serves as excellent insulation against the cold, and their soft, padded feet are low-impact on the delicate Andean terrain. With domestication and the global popularity of alpaca fiber, alpacas have been introduced to various parts of the world, including North America, Europe, Australia, and New Zealand.

Despite their Andean origins, they’ve proven to be incredibly adaptable and can thrive in various climates, from the chilly Canadian winters to the hot Australian summers.

Alpaca in the Andes


Alpacas are diurnal, active during the day, with peak activities occurring during dawn and dusk. These social creatures live in family groups consisting of a dominant male, females, and their offspring. Adult males without a family group of their own may form “bachelor” herds.

Alpacas have a unique way of communicating through a series of sounds. The most common is a gentle humming sound, used in various situations such as curiosity, contentment, worry, or boredom. Other sounds include a piercingly high alarm call to alert the herd of potential danger and aggressive screeches, roars, or clucking during disputes.

Diet and Feeding Behavior

As herbivores, alpacas primarily feed on grass, hay, and silage (fermented, high-moisture stored fodder). Their feeding behavior is similar to that of other ruminants, as they graze for several hours a day, mainly in the mornings and evenings.

Alpacas have a pseudo-ruminant digestion process. While they only have one stomach, it has three compartments, which allow efficient extraction of nutrients even from poor-quality forage.


In their native Andean habitat, alpacas’ main predators include pumas, foxes, and occasionally, Andean condors that may target weak or juvenile individuals. In other parts of the world where alpacas are farmed, potential predators vary.

In North America, for example, alpacas may be preyed upon by coyotes, wolves, or large birds of prey. It is important to note that due to the alpaca’s domestication, human activities and predation by domestic dogs can also pose significant threats.

Reproduction and Life Cycle

Alpacas have unique breeding habits; they are induced ovulators, which means the act of mating itself causes the female to ovulate. Alpaca males, known as machos, are ready to breed by the age of 2 to 3 years, while females, or hembras, can reproduce from 1 to 2 years of age.

The gestation period for alpacas is about 11 to 12 months, typically resulting in a single offspring, known as a cria. Twin births are rare. After giving birth, the female can be bred again after about two weeks. The cria is usually weaned at around six months of age.

Alpacas have a unique “matriarchal” system. Mothers with their young often group together, and a few experienced females effectively watch over the younger ones’ crias.

Conservation and Threats

Alpacas are not classified as endangered or threatened, with populations being healthy in their native South America, and their global population boosted by their popularity in farming and as pets. They are resilient animals and adaptable to various environments, making them relatively robust in the face of habitat changes.

However, they are not entirely without threats. Climate change, which affects the grasslands and high-altitude environments where they typically graze, could potentially impact their populations. Overgrazing can also lead to the degradation of their natural habitats.

Conservation efforts for alpacas are generally tied to wider environmental conservation efforts. Given their economic value, there is also a strong incentive for farmers to ensure their populations remain healthy. Sustainable farming practices and responsible stewardship of grazing lands are key to maintaining alpaca populations for the future.

Fun Facts

  1. Alpacas have been domesticated for thousands of years. In fact, the Moche people of Northern Peru often used alpaca images in their art.
  2. There are no wild alpacas. All the ones in existence today are domesticated descendants of the vicuña, a South American ruminant that lives in the high alpine areas of the Andes.
  3. Alpacas are very social creatures. They are usually seen in family groups consisting of a dominant male, females, and their offspring.
  4. Despite their fluffy appearance, only a small portion of an alpaca’s body weight is actually their wool. Their fiber is lighter and warmer than sheep’s wool.
  5. Alpacas hum! It’s a common vocalization, often signaling curiosity, contentment, anxiety, or caution to each other.

Frequently Asked Questions

What’s the difference between alpacas and llamas?

Alpacas are generally smaller than llamas and have a different physical appearance, including a shorter face, more blunt ears, and denser wool. They’re also reared for their wool rather than as pack animals.

How long do alpacas live?

The average lifespan of an alpaca ranges from 15 to 20 years, although some have been known to live longer.

What do alpacas eat?

Alpacas are herbivores and their diet primarily consists of grass and hay. They may also be fed alpaca pellets for additional nutrition.

Are alpacas friendly?

Yes, alpacas are usually friendly and gentle. However, they are also shy and can get nervous around people or animals they are not familiar with.

How fast can an alpaca run?

An alpaca can run at speeds of up to 35 miles per hour (56 km per hour) when necessary, but they usually move at a slow, leisurely pace.
