Abstract
The family Camelidae comprises the only extant members of the suborder Tylopoda and includes the Afro-Asian and South American camelid species. The Afro-Asian, or Old World, camelids include the domestic Bactrian camel (Camelus bactrianus), wild Bactrian camel (Camelus ferus), and domestic dromedary camel (Camelus dromedaries). Wild Bactrian camel populations are restricted to northern China and southern Mongolia and are genetically distinct species to their domesticated relatives. Although no true wild populations of dromedary camels exist, there are several feral populations present in different regions of the globe, with a notably large population residing in the Australian Outback. The South American, or New World, camelids include the domesticated alpaca (Vicugña pacos) and llama (Lama glama) and the wild guanaco (Lama guanaco) and vicuña (Vicugña vicugña). As the name implies, all South American camelids were originally native to South American.
