Interesting facts about the bactrian camel:
The bactrian camel is the largest mammal in its native range and is the largest living camel.
The two humps on the back are composed of fat (not water as is sometimes thought).
They have a remarkable ability to go without water for months at a time, but when water is available they may drink up to 57 liters at once.
Speeds of up to 65 kilometres per hour (40 mph) have been recorded, but they rarely move this fast.
They are primarily herbivorous. They have tough mouths that can withstand sharp objects such as thorns. They are able to eat plants that are dry, prickly, salty or bitter, and can ingest virtually any kind of vegetation.
The first time food is swallowed, it is not fully chewed. The partly masticated food (called cud) goes into the stomach and later is brought back up for further chewing. Wow, I didn’t know camels could do that!
