Bactrian camels can be a foot taller. Camels can run at up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph). [14] Bactrian camels weigh 300 to 1,000 kg (660 to 2,200 lb) and dromedaries 300 to 600 kg (660 to 1,320 lb). The widening toes on a camel's hoof provide supplemental grip for varying soil sediments.

The Bactrian camel shares the genus Camelus with the dromedary (C. dromedarius) and the wild Bactrian camel (C. ferus).The Bactrian camel belongs to the family Camelidae. [1] [5] The ancient Greek philosopher Aristotle was the first European to describe the camels: in his 4th century BCE History of Animals, he identified the one-humped Arabian camel and the two-humped Bactrian camel.
Dromedary camels, bactrian camels, llamas, and alpacas are all induced ovulators. [8] The three Afro-Asian camel species have developed extensive adaptations to their lives in harsh, near-waterless environments. Wild populations of the Bactrian camel are even able to drink brackish water, and some herds live in nuclear test areas. [9]
Camelops is an extinct genus of camel that lived in North and Central America from the middle Pliocene (from around 4-3.2 million years ago) to the end of the Pleistocene (around 13-12,000 years ago).
Guanacos live in herds composed of females, their young, and a dominant male. Bachelor males form separate herds. While reproductive groups tend to remain small, often containing no more than 10 adults, bachelor herds may contain as many as 50 males. They can run at 56 km/h (35 mph) per hour, often over steep and rocky terrain. [21]
Live camels are occasionally exported to Saudi Arabia, the United Arab Emirates, Brunei, and Malaysia, where disease-free wild camels are prized as a delicacy. Australia's camels are also exported as breeding stock for Arab camel racing stables, and for use in tourist venues in places such as the United States. [61]
Nomadic people traditionally travel by animal, canoe or on foot. Animals include camels, horses and alpaca. Today, some nomads travel by motor vehicle. Some nomads may live in homes or homeless shelters, though this would necessarily be on a temporary or itinerant basis. [citation needed] Nomads keep moving for different reasons.
The nuclear testing caused no apparent ill effects on the camels, which continued to breed normally. After China signed the Comprehensive Test Ban Treaty in 1996, the camels were reclassified as an endangered species. [4] Since then, human incursions into the area have caused a sharp drop in the camel population. [5]
