A camel adapts easily in a desert due to

The camel's primary adaptation for desert survival is its hump, which serves as a reservoir for fatty tissue rather than water [t2]. This fat acts as an energy reserve during periods of food and water scarcity [t3]. When this fat is metabolized, it produces metabolic water, which helps the camel withstand prolonged starvation and dehydration [t5]. Concentrating fat in the hump also prevents it from acting as an insulating layer across the body, allowing excess heat to escape more efficiently [t2][t3]. While camels have unique oval-shaped Red Blood Cells (RBCs) that can withstand high osmotic variation and flow during dehydration [t1][t2], they are non-nucleated like other mammals; the misconception of nucleated RBCs is common but scientifically incorrect for mammals. Furthermore, the idea of 'water cells' in the stomach is a myth; camels actually release water from their digestive tract slowly to maintain equilibrium [t2].
