1. Camels eat hay and salt. Because it often travels long distances, hay is digested slowly. Camels like to eat plants with thorns, hairs, strong smells, and salt-alkali that other livestock do not want to eat. White thorns and wormwood are all camels' delicacies.

2. Camels can tolerate hunger and thirst. They can drink enough water for several days without water, and can still move around in hot and arid desert areas.

3. The nostrils can be opened and closed, and there are enough fleshy pads and thick skin, suitable for walking in the desert. There are fleshy peaks on the back, which store fat. The stomach has three chambers, and the first stomach chamber contains 20 to 30 water. It can store water. Red blood cells can expand greatly to absorb water and store water. Therefore, it can withstand hunger and thirst and can go without eating or drinking for many days. Once it encounters water plants, it can drink a lot of water and store it.
