Ecological niche
In ecology, a niche is a term describing the relational position of a species or population in its ecosystem to each other; e.g. a dolphin could potentially be in another ecological niche from one that travels in a different pod if the members of these pods utilize significantly different food...

s like beetles, dragonflies and crickets, and possibly even snails. But the larger species may also have hunted small mammals, reptiles and birds.

In the Late Miocene subepoch, what is at present Italy was mainly a group of small islands and only at a later date did majority of these join with the mainland. It is known that animals on these islands sometimes evolved quite differently than they would elsewhere. So it is possible that Deinogalerix may have lived exclusively in the Gargano.
