What purpose do the shallower tunnels in a Zokor burrow system typically serve?

Answer

They function as foraging routes leading toward the surface

The extensive tunnel networks constructed by zokors are highly functional, featuring different levels of depth tailored to specific activities. The deeper, more permanent chambers are reserved for essential functions like nesting, resting, and secure storage. In contrast, the shallower tunnels are strategically created to serve as main transit lines and foraging routes. These closer-to-the-surface pathways allow the zokor to efficiently access local root systems and vegetation stems without having to construct entirely new pathways or venture far from the safety of their established subterranean matrix.
