Physical description.
A camel is an even-toedungulate within the genus Camelus, bearing distinctive fatty deposits known as humps on its back. There are two species of camels: the dromedary or Arabian camel has a single hump, and the Bactrian camel has two humps.
Place of origin.
They are native to the dry desert areas of West Asia, and Central and East Asia, respectively.
Life expectancy.
The average life expectancy of a camel is 40to 50 years. A fully grown adult camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. The hump rises about 30 inches (76.20 cm) out of its body. 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).
Camels are sexually mature at about 4 years old. Females reproduce till 30 years old, delivering one offspring at twoyears, and even more if food is abundant.
Habitat
There is the concept that camel is a strictly desert animal. Some say that camels are at the origin savanna animals, but wild camels were eliminated in the savanna by lions, against which they were defenseless, resisting in the desert due to the lack of big predators.

This is proved by the fact that dromedaries thrive better in less aridareas of their range: 3.6 individuals/square kilometer in Eastern Africa, 8.7 in Somalia, 1.7 in India, while their densities plummet to 0.4 in de deserts of west Africa, 0.14 in North Africa and Arabia and 0.08 in Sahara.
Abilities.
Their ability to withstand long periods without water is due to a series of physiological adaptations. Their red blood cells have an oval shape, unlike thoseof other mammals, which are circular. This is to facilitate their flow in a dehydrated state.
Size
A camel stands from 1.8 to just over 2 metres tall at the shoulders, and weighs from 250 to 680 kilograms. Its rope like tail is over 50 centimetres long. Camels seem larger than they are because of their thick, woolly fur, which may be all shades of brown, from nearly white to almost black. AnArabian camel's fur is short and helps protect its body from the heat. A Bactrian camel's fur is longer. It may grow about 25 centimetres long on the animal's head, neck, and humps.
The young at birth has 25-50 kg (60-120 pounds) and it is 1.2 m (4 ft) tall. The female has 4 tits, and produces 15 liters of milk daily (87 % water, 3.5-5 % fats and lactose (milk sugar), 3-4 % proteins. Weaningoccurs when the young is one year old (rarely at 3 years old), but people force it at 7-10 months, to use the mother's milk.
Food
The food that camels eat depend on whether they are domesticated, feral or living in zoos. In the wild, camels will eat just about anything as it is very hard to find food. They eat plants, dried leaves, seeds, bones, fish meat and even leather! Domesticated camels(those raised by people) are usually fed dates, grass, wheat and oats. In zoos, camels are fed hay and dry grass- about 3.5 kilograms of food everyday!
Human use
TOURISM
Camel Rides are now available all over Australia, from Broome to Burnie and Cairns to Kangeroo Island. There are over 40 Camel Farms operating in Australia to primarily to target the tourist trade, providing Camel ridesand Safari Treks.
On Camel Safaris, the distinctive landforms of the Australian Countryside, the wildlife and the serenity, allows the tourist a unique opportunity to enjoy and understand the environment.
MILK
Camel milk has similar chemical characteristics to cattle milk. The period of lactation is longer than cattle, however the daily production is lower. The advantage of Camels is...
