A mole’s diet primarily consists of earthworms and other small invertebrates found in the soil, and a variety of nuts. The mole runs are in reality “worm traps”, the mole sensing when a worm falls into the tunnel and quickly running along to kill and eat it. Because their saliva contains a toxin that can paralyze earthworms, moles are able to store their still-living prey for later consumption. They construct special underground “larders” for just this purpose; researchers have discovered such larders with over a thousand earthworms in them. Before eating earthworms, moles pull them between their squeezed paws to force the collected earth and dirt out of the worm’s gut.–Wikipedia
