Answer
The water saving methods in a camel are:
- Little and thick urine — When deprived of water, the camel passes out very little urine and it is quite thick.
- Semi-dry faeces — The dung passed out is quite dry.
- Perspires very little — The camel can tolerate high outside temperature up to 40°C to 45°C as its own body temperature can go up to 41°-42°C and therefore the need to perspire is reduced.
- Slow breathing — Certain amount of moisture is always lost due to evaporation in the respiratory passages during breathing. Slower the rate of breathing, lesser the loss of water as water vapour in the air breathed out.
- Water "storage" in muscles — The camel's muscles can withstand the shortage of water and can shrink considerably. Once the water is available, the camel can drink sufficient water and the muscles swell up.
- Water from the "fat" of the hump — While starving, the fat is oxidized to yield energy as well as water.
