Camels are very adaptable

 A camel can drink salt water from the Dead Sea.Its blood pressure does not rise because it's kidneys filter the water to make it drink fresh,separating the water from the salt.

            Camels can eat thorns and their stomachs and intestines are not harmed because their saliva is like acid,which dissolves the thorns and eats them as if they were bread and dough.Therefore,the people of the desert,if thorns fall on their hand or feet,put camel saliva on them and it dissolves the thorns.
