Lama glama, a member of the camel family (Camelidae) found only in South America. The llama (see illustration) is an artiodactyl, or even-toed ungulate, belonging to the mammalian family Camelidae. It has two toes on each foot. The llama is a domesticated South American camelid and is found in the Andean highlands, particularly in Peru and Bolivia. The upper lip of the llama is cleft and prehensile. The animal has a long neck, and it attains a maximum length of less than 2.4 m (8 ft) and a maximum weight of nearly 136 kg (300 lb). A single young is born after a gestation period of approximately 11 months. The maximum life span is about 20 years. Like other members of the camel family, the llama is herbivorous. It has 36 teeth, with a dental formula of I 1/3, C 1/1, Pm 3/3, M 3/3 × 2. It also lacks a gallbladder. Many interesting crosses have occurred among the different camel breeds in South America (see table). See also: Artiodactyla; Breeding (animal); Camel; Mammalia; South America
