Because of specialized bone and muscle construction, moles can exert a lateral digging force equivalent to 32 times its body weight. As a comparison, a 150 lb. man would be able to exert a 4800 lb. lateral force.
For moles to dig one meter of tunnel requires between 400 and 4,000 times as much energy as does walking for the same distance on the surface.
A 5 ounce mole will consume 45 to 50 lbs. of worms and insects per year.
