What survival strategy is directly underpinned by the physical adaptation of strong limbs and sharp claws in Xerus species?
Answer
Retreating underground into complex networks to escape predators and the harsh midday heat
The highly specialized structure of the *Xerus* limbs—characterized by strong build and notably long, sharp claws—is directly linked to their primary survival strategy. As obligate burrowers, these physical traits are essential tools for excavation. They enable the squirrels to vigorously dig and maintain their underground networks. By creating these deep retreats, the squirrels secure a safe haven that serves the dual purpose of evading surface predators that might attack from above, and providing a refuge from the extreme temperatures encountered during the harsh midday heat characteristic of their arid habitats.
