Adaptation Mechanisms of Camels (Camelus dromedarius) for Desert Environment: A Review

Abstract

Mulu Gebreselassie Gebreyohanes and Awol Mohammed Assen

Dromedary camels have a number of adaptation mechanisms that help them to survive successfully in dry and arid climates in which there is shortage of water and high environmental temperature. For survival in desert environment, camels have physiological, anatomical and behavioral adaptation mechanisms. Water conservation ability, the unique features of blood, thermoregulation, and efficient digestion and metabolism are among the physiological adaptations. Anatomically the nature of skin coat, eye, nostril and lips, large body size and long height and large foot pads contribute for their survival. Moreover the feeding, drinking, thermal and sexual behavior of camels also plays a major role in succeeding their existence in the desert environment. Despite of their great contribution for the livelihood of many pastoralists in different parts of the world in which other animals face difficulties, camels are the most neglected domestic animals by the scientific community. Therefore the value camels should have to get emphasis and awareness should have to be created to the community about health care and management of camels to improve their production and productivity.
