no, I changed my answer there is a misconception that camels drink less water.A camel's water intake varies according to his environment, his exertion level, and the amount of fat in his hump. A thirsty camel can drink more than 30 gallons of water in less than 15 minutes. 1.1 A typical camel can drink 200 liters (53 gallons) of water in three minutes. they drink a lot of water but can also go a long time without drinking water...hope it helps
