Also, The camel travels all over  deserts, bearing all of these and get along with these concepts. Because of that, camels are known by ships of desert. Although they live in the harshest areas all over the world, they are categorized as domestic animals. One of the camels' features is storing water and fat in their humps. Before cars, trains and transportation vehicles were invented, people used to travel riding camels and loading camels all the luggage.  Nowadays, many people in Saudi Arabia like to have camels in order to take care of them. Why camels save water and fat in their humps? Each animal knows its environment well. Camels know that desert doesn't have a lot of water's lakes. The proximate cause of storing water and fat in humps is the fear of not finding water and food that keep camels alive. Also, the other proximate cause is to keep them alive for many days without eating and drinking water. Camels are considered  mammals. That means camels have same features that other mammals have such as the operation of rumination.  The operation of rumination is an operation that allows camels to swallow food and bring them back again to complete chewing. The ultimate cause of this operation is to eat food as much as camels can and chewing it later at the night.
In conclusion, the ship of the desert means bearing the harshest environment. Also, camels are not called by that name because of their shapes or sizes.
