The Part-Time Residents of Deep Caves

Some animals are cave guests that rely on the dark underground for shelter but cannot survive there permanently. These creatures constantly commute between the surface and the abyss to stay alive.

Unlike permanent cave dwellers that evolve to live in total darkness, these transient visitors treat caves like a temporary hotel. They often retreat to the entrance to escape harsh weather or find food, only to head back outside for essential resources. This unique behavior separates them from creatures that never see the light of day. It is a fragile survival strategy that keeps them tethered to the edge of two very different worlds.
