If you have half this number of such entities, then you have half a mole of such entities.


A mole is a type of insectivore that lives under ground, burrowing holes. It feeds on small invertebrate animals living under ground. There are also similar-looking but herbivorous rodents called mole rats that enjoy a similar life-style and are commonly called "moles".
