2. Gerbils: These small nocturnal rodents feed on various plants, seeds, and bulbs, mostly found near water sources.
3. Gazelles: Slender-horned gazelles and Dorcas gazelles are able to survive on sparse vegetation and can store water in their bodies for long periods.
4. Camels: Known for their ability to survive in the desert, camels feed on a variety of desert vegetation and can drink large quantities of water quickly.
5. Fennec Foxes: These small, big-eared foxes are opportunistic omnivores that mostly feed on rodents, reptiles, birds, and berries.
6. Barbary Sheep: Found in the mountains of the Sahara, these herbivores graze on grasses, shrubs, and leaves.
7. Addax: These long-horned antelopes feed on grasses, shrubs, and herbs.

2. Ants: Diverse ant species, such as harvester ants and desert ants, play a crucial role in the decomposition of organic matter and feed on seeds.
It's important to note that the Sahara Desert covers an extensive area, with different regions having slightly varying ecosystems and conditions, leading to local variations in the diets and habitats of desert animals.
