The four forms commonly distinguished by the inhabitants of South America are recognized as distinct species, though with difficulties in defining their distinctive characteristics. Many are also descended from ancestors that have previously been domesticated, a state that tends to produce a certain amount of variation from the original type. The question is complicated by the circumstance of the great majority of individuals that have come under observation being either in a completely or partially domesticated state. In essential structural characteristics, as well as in general appearance and habits, all the animals of this genus very closely resemble each other, so whether they should be considered as belonging to one, two, or more species is a matter of controversy among naturalists. The tail is short, and fibre is long, woolly and soft. The feet are narrow, the toes being more separated than in the camels, each having a distinct plantar pad. The ears are rather long and slightly curved inward, characteristically known as "banana" shaped. The nasal bones are shorter and broader, and are joined by the premaxilla.
The skull generally resembles that of Camelus, the larger brain-cavity and orbits, and less-developed cranial ridges being due to its smaller size.

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. In the lower jaw, the three incisors are long, spatulate, and procumbent the outer ones are the smallest. 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. The isolated canine-like premolar that follows in the camels is not present. In the upper jaw, a compressed, sharp, pointed laniariform incisor near the hinder edge of the premaxilla is followed in the male at least by a moderate-sized, pointed, curved true canine in the anterior part of the maxilla. Dentition of adults: incisors 1 / 3 canines 1 / 1, premolars 2 / 2, molars 3 / 3 total 32. The following characteristics apply especially to llamas. According to Aymara eschatology, llamas will return to the water springs and lagoons where they come from at the end of time. The Heavenly Llama is said to drink water from the ocean and urinates as it rains. In Aymara mythology, llamas are important beings. As of 2007, there were over seven million llamas and alpacas in South America and over 158,000 llamas and 100,000 alpacas, descended from progenitors imported late in the 20th century, in the United States and Canada. By the end of the last ice age (10,000–12,000 years ago), camelids were extinct in North America. The ancestors of llamas are thought to have originated from the Great Plains of North America about 40 million years ago, and subsequently migrated to South America about three million years ago during the Great American Interchange. The name llama (in the past also spelled "lama" or "glama") was adopted by European settlers from native Peruvians. When using a pack, they can carry about 25 to 30% of their body weight for 8 to 13 km (5–8 miles). Llamas can learn simple tasks after a few repetitions. Their wool is soft and contains only a small amount of lanolin. Llamas are social animals and live with others as a herd. The llama ( Lama glama) is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures since the Pre-Columbian era.
