And in underground tunnels?
There are groups of terrestrial animals that eat insects, worms and other invertebrates. An example of them are moles, that can be rarely seen on the surface and can be identified by the small earth mounds. In fact they dig underground tunnels that are all interlinked. Some of them are used to make nests.
Moles are active animals both at night and during the day. They have a long muzzle and a very sensitive smell, while the eyes are particularly small (some European small moles are blind). Their forelegs are very wide, and like small shovels they are useful to dig. They are able to feel soil vibrations very well. Other animals like the badger and the rabbit shelter in ground holes during the day, night, or when they hibernate.
