The Sahara Desert is one of the most fascinating and expansive landscapes on Earth. A fun fact about the Sahara is that it is not entirely covered in sand; only about 25% of the Sahara is sandy dunes, with the rest consisting of gravel plains, rocky plateaus, and even mountains that receive snowfall. This diverse terrain is home to unique ecosystems and a rich history.

How Large is the Sahara Desert?
The Sahara Desert is the largest hot desert in the world, covering approximately 9.2 million square kilometers (3.6 million square miles). It spans across 11 countries in North Africa, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, and Tunisia.

Thousands of years ago, it was a lush, green region with abundant lakes and vegetation.
What Kind of Wildlife Lives in the Sahara Desert?
Despite its harsh conditions, the Sahara supports a variety of wildlife. Some of the animals that have adapted to this environment include:
- Fennec Fox: Known for its large ears, which dissipate heat.
- Addax Antelope: An endangered species that can survive without water for long periods.
- Dromedary Camel: Often called the "ship of the desert," it is perfectly adapted to the Sahara’s extreme conditions.
Birds, reptiles, and insects also thrive here, each uniquely adapted to the desert’s challenges.
