They live in the desert, so they don't get a lot of access to water.
a camel produces very little sweat and urine
because some camels have very little water, or they preserve water in their humps
sweat
Very little sweat and urine is not a structural adaptation. It only means your body is dehydrated and that all the fluid is being absorbed. If it is only no urine, there may be a problem with your urethra. Not urinating is very bad for the body as toxins build up in the body therefore, very little sweat and urine is not a structural adaptation.
To conserve water
It is advantageous for survival to void little liquid in hot conditions. A camel does not store water in its humps. The water that it drinks is absorbed into its bloodstream.
it is b/c they dont drink very often. they can drink water once a week, if they find water until then. if you only drank water every few days and only lived off a couple dry shrubs and fat in your hump, i dont think youd urinate as often as you do.....
Yes, it is very common that Hamsters sweat sometimes even in their urine ( PEE ) .
Very little alcohol is excreted as sweat.
You must see your doctor.
That depends on the input, the weather, and the amount of physical activity. If you take in about 2 liters of water a day, and sweat a little, a liter of urine is normal...that would be one very full bladder.
They don't need to drink water very often.
