Having created tunnels the mole is required to finding its way around, the tunnels may be adjoining tunnels from different areas, a labyrinth of feeding tunnels or a tunnel not used since the last breeding season. What ever the circumstances the mole is required to navigate or find its way from one place to another..
How do they do this?
They do this by using a special sense called a kinaesthetic sense, we all have one. It is an imprinted pattern of memory, but the moles kinaesthetic sense is used in conjunction with other special abilities that we also have but cannot use as efficiently as them.
The moles can remember every tunnel, its length, the turns and the junctions, it may have dug to build the complex itself or have entered into a previously built one made by another mole, but by using these amazing special senses the mole soon has a knowledge of that environment.
