沙鼠, also known as the sand rat, is a small rodent found primarily in arid regions of North Africa and the Middle East. These creatures are well-adapted to their desert habitats, featuring a sandy-colored fur that provides camouflage against predators. They typically have a robust body, short legs, and long tails, which help them navigate their environment. These rodents are primarily nocturnal, foraging for seeds, roots, and insects during the cooler night hours. Their burrowing behavior allows them to escape the extreme heat of the day and provides a safe place for nesting. The sand rat plays a vital role in its ecosystem by aiding in seed dispersal and serving as prey for various desert predators.
