Premise: Interstitial spaces are usually not much larger than the organisms found within them. Being hemmed in on all sides has resulted in these organisms typically being smaller and having shortened appendages compared to the inhabitants of larger underground spaces. (3) Unlike caves and interstitial spaces, shallow subterranean habitats are always found near (<10 m from) the surface, are small and usually contain lots of organic matter for critters to eat
