Imagine trying to survive in hot, dry deserts in Africa and Asia. For many animals, a habitat like this would be impossible. Yet the camel, a mammal about 2 meters tall at the hump, thrives there, thanks to features that scientists call adaptations: traits that help a living thing survive in its environment.
Consider a hump full of fat: this adaptation gives it energy when food is hard to find. The word hump refers to a rounded lump on the back that stores fat. Equally important is two rows of long eyelashes, which keep blowing sand out of its eyes. Without these traits, the camel would struggle to last a single season.
As a herbivore, the camel is an animal that eats only plants; it depends on dry grasses, thorny plants and leaves. Its behavior matters as much as its body: it can walk for days across the sand without stopping to drink. Behaviors like this are adaptations too, even though you cannot see them in a photograph.
The next generation faces the same challenges. Young camels, called calves, depend on their surroundings and on adult care. A calf can walk just a few hours after it is born.
Perhaps most remarkable of all: a thirsty camel can drink more than 100 liters of water in about ten minutes. Facts like this remind us that every animal's body tells a story about the place it lives.
