Lama glama (Linnaeus, 1758)

The llama (Lama glama) is a large camelid that originated in North America and then later on moved on to South America. The term llama is sometimes used more broadly, to indicate any of the four closely related animals that make up the South American branch of the family Camelidae: the true llama, the vicuña, alpaca, and guanaco. They were used as a system of transportation for the Incas.

Differentiating characteristics between llamas and alpacas are that llamas are larger and have more elongated heads. Alpacas are sometimes considered to have more valuable fiber, as it is typically finer than that of a llama. The most apparent visual difference between llamas and camels is that camels have a hump or humps and llamas do not.

Classification

Although they were often compared by early writers to sheep and spoken of as such, their affinity to the camel was very soon perceived. They were included in the genus Camelus in the Systema Naturae of Linnaeus. They were, however, separated by Cuvier in 1800 under the name of Lama along with the alpaca and the guanaco. Vicuñas are in genus Vicugna. The animals of the genus Lama are, with the two species of true camels, the sole existing representatives of a very distinct section of the "Artiodactyla" or even-toed ungulates, called Tylopoda, or "bump-footed," from the peculiar bumps on the soles of their feet, on which they tread. This section thus consists of a single family, the Camelidae, the other sections of the same great division being the Suina or pigs, the Tragulina or chevrotains, and the Pecora or true ruminants, to each of which the Tylopoda have more or less affinity, standing in some respects in a central position between them, borrowing as it were some characters from each, but in others showing great special modifications not found in any of the other sections.

The discoveries of a vast and previously unsuspected extinct fauna of the American continent of the Tertiary period, as interpreted by the palaeontologists Leidy, Cope, and Marsh, has thrown a flood of light upon the early history of this family, and upon its relations to other mammals.

It is now known that llamas at one time were not confined to the part of the continent south of the Isthmus of Panama, as at the present day, for their remains have been abundantly found in the Pleistocene deposits of the region of the Rocky Mountains, and in Central America, some attaining a much larger size than those now existing. Some species of llamas did stay in North America during the last ice ages. 25,000 years ago, llamas would have been a common sight in modern-day California, Texas, New Mexico, Utah, Missouri, and Florida. These North American llamas belong to a single genera, Hemiauchenia, which is extinct.

Many camel-like animals exhibiting different genetic modifications and a gradual series of changes, coinciding with the antiquity of the deposits in which they are found, have been traced from the thoroughly differentiated species of the modern epoch down through the Pliocene to the early Miocene beds. Their characters having become more generalized, they have lost all that especially distinguishes them as Camelidae: they are merged into forms common to the ancestral type of all the other sections of the Artiodactyles.

Hitherto none of these annectant forms have been found in any of the fossiliferous strata of the Old World; it may therefore be fairly surmised (according to the evidence at present before us) that the Americas were the original home of the Tylopoda, and that the true camels have passed over into the Old World, probably by way of north Asia. Gradually driven southward, perhaps by changes of climate, and having become isolated, they have undergone further special modifications. Meanwhile, those members of the family that remained in their original birthplace have become, through causes not clearly understood, restricted solely to the southern or most distant part of the continent. There are few groups of mammals for which the palaeontological history has been so satisfactorily demonstrated as the llama.

Characteristics

The following characters apply especially to llamas. Dentition of adults:-incisors 1/3 canines 1/1, premolars 2/2, molars 3/2; total 32. In the upper jaw there is a compressed, sharp, pointed laniariform incisor near the hinder edge of the premaxilla, followed in the male at least by a moderate-sized, pointed, curved true canine in the anterior part of the maxilla. The isolated canine-like premolar which follows in the camels is not present. The teeth of the molar series which are in contact with each other consist of two very small premolars (the first almost rudimentary) and three broad molars, constructed generally like those of Camelus. In the lower jaw, the three incisors are long, spatulate, and procumbent; the outer ones are the smallest. Next to these is a curved, suberect canine, followed after an interval by an isolated minute and often deciduous simple conical premolar; then a contiguous series of one premolar and three molars, which differ from those of Camelus in having a small accessory column at the anterior outer edge.

The skull generally resembles that of Camelus, the relatively larger brain-cavity and orbits and less developed cranial ridges being due to its smaller size. The nasal bones are shorter and broader, and are joined by the premaxilla.

Vertebrae:

• cervical 7,
• dorsal 12,
• lumbar 7,
• sacral 4,
• caudal 15 to 20.

Ears are rather long and pointed. There is no dorsal hump. Feet are narrow, the toes being more separated than in the camels, each having a distinct plantar pad. The tail is short, and fur is long and woolly.

In essential structural characters, as well as in general appearance and habits, all the animals of this genus very closely resemble each other, so that whether they should be considered as belonging to one, two, or more species is a matter of controversy among naturalists.

The question is complicated by the circumstance of the great majority of individuals which have come under observation being either in a completely or partially domesticated state. Many are also descended from ancestors which have previously been domesticated; a state which tends to produce a certain amount of variation from the original type. It has, however, lost much of its importance since the doctrine of the distinct origin of species has been generally abandoned. The four forms commonly distinguished by the inhabitants of South America are recognized by some naturalists as distinct species, and have had specific designations attached to them, though usually with expressions of doubt, and with great difficulties in defining their distinctive characteristics.

These are:

• the llama, Auchenia glama (Linn.), or Lama peruana (Tiedemann);
• the alpaca, A. pacos (Linn.);
• the guanaco or huanaco, A. huonaeus (Molina); and
• the vicuña, A. vicugna (Molina), or A. vicuiena, (Cuv.).

The llama and alpaca are only known in the domestic state, and are variable in size and colour, being often white, black, or piebald. The guanaco and vicuña are wild and endangered, and of a nearly uniform light-brown colour, passing into white below. They certainly differ from each other, the vicuña being smaller, more slender in its proportions, and having a shorter head than the guanaco. The vicuña lives in herds on the bleak and elevated parts of the mountain range bordering the region of perpetual snow, amidst rocks and precipices, occurring in various suitable localities throughout Peru, in the southern part of Ecuador, and as far south as the middle of Bolivia. Its manners very much resemble those of the chamois of the European Alps; it is as vigilant, wild, and timid. The wool is extremely delicate and soft, and highly valued for the purposes of weaving, but the quantity which each animal produces is minimal.

Behavior

Llamas who are well-socialized and brought up by loving families are very friendly and pleasant to be around. They are extremely curious and most will approach people easily. Occasionally, llamas do spit at each other or people. The habit of spitting is a defense mechanism. However, usually, a llama would prefer to run away before confronting their assumed aggressor. The spitting behavior is believed to be a direct result of their usually shy disposition .

The sound of the llama making groaning noises or going "mwa" is often a sign of fear or anger. If a llama is agitated, she or he will lay his or her ears back. One may determine how agitated the llama is by the materials in the spit. The more irritated the llama is, the further back into each of the three stomach compartments it will try to draw materials from, for its spit.

One of the main uses for llamas at the time of the Spanish conquest was to bring down ore from the mines in the mountains. Gregory de Bolivar estimated that in his day as many as three hundred thousand were employed in the transport of produce from the Potosí mines alone, but since the introduction of horses, mules, and donkeys, the importance of the llama as a beast of burden has greatly diminished.
