Even if it doesn't eat all the worms, there is no waste. Earthworms regenerate at the head, so they grow a whole new body and wiggle away. It is the mole's constant need for food that drives it to drill through even the most compacted soils. A muscular cylindrical body equipped with oversized front feet that look like clawed paddles allows the mole to scrape through the earth in a swimming-like motion. Forefeet push the soil against the side of a tunnel and compact it.
Back feet grip the tunnel wall for leverage.
In good soil, moles can travel up to 30 yards an hour and will easily do 50-plus when in rut. They can run 80 feet per minute in an established tunnel. Moles create elaborate tunnel systems below the ground. Here they breed, raise young and catch insects. In the spring, when the soil warms and insect activity increases, moles bear their young in nests.
