 When the camel exhales, water vapor becomes trapped in their nostrils and is reabsorbed into the body as a means to conserve water.Camels eating green herbage can ingest sufficient moisture in milder conditions to maintain their bodies' hydrated state without the need for drinking.The camel's thick coat insulates it from the intense heat radiated from desert sand; a shorn camel must sweat 50% more to avoid overheating.
