Tribal Elder with Camels, Oman, 1992Photograph by James StanfieldA Bedouin tribal elder tends camels at nightfall in Sahamah, Oman. Arabian camels, also called dromedaries, have been domesticated for some 3,500 years. Valued as pack animals, they can carry large loads for up to 25 miles (40 kilometers) a day. They also have a number of special physical adaptations that help them thrive in desert conditions.
