Below are some extraordinary facts about Moles:
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.
A moles surface tunneling or probes can be dug at about 18 feet per hour. A moles speed through existing tunnels is about 80 ft. per minute.
Moles contain twice as much blood and twice as much red hemoglobin as other mammals of similar size, allowing the mole to breath easily in its underground environment of low oxygen and high carbon dioxide.
