Camels - Adaptation
Despite some difference in size, all of the Camels are similar in structure. Having evolved in a semi-desert environment, they have developed sophisticated adaptations for coping with heat and dehydration. The long eyelashes and sealable nostrils keep out dust in the sandstorms. The two toes have undivided soles and are able to spread widely, which is useful for walking on sand. Thick callosities on the joints of the legs and on the chest, upon which Camels rest in kneeling position, enable them to withstand the hot sand.
Dromedary Camels don't store water, but are able to safely loose such quantities of body water that would be lethal in other animals. Dromaderies' plasma volume is maintained at the expense of tissue fluid, their erythrocytes continue to circulate even in situations of increased blood viscosity. The camel can take in large amounts of water, because it's absorbed very slowly, allowing time for equilibration, besides, their erythrocytes can swell to 240% of normal size. (Other species can go to 150%.) Camels are able to drink brackish or salt water.

The kidneys of all Camels concentrate the urine as thick as syrup to reduce water loss.
Their fecal pellets contain no water and can be used for fuel. Camels are able to have fluctuations in body temperature. During the day, the Camels' body acts as a heat sink, and during the cold night, excess body heat is dissipated by conduction.
