Approximately how much earth per day can a mole shift?

Moles are small mammals adapted to a subterranean lifestyle. They have cylindrical bodies, velvety fur, very small, inconspicuous ears and eyes, reduced hindlimbs and short, powerful forelimbs with large paws adapted for digging. The term "mole" is especially and most properly used for "true moles" of the Talpidae family in the order Soricomorpha found in most parts of North America, Asia, and Europe.

The mole is the only mammal to live solely underground and they achieve this because they have a greater proportion of red blood cells than other mammals. This helps them to live in an environment where oxygen levels are low, typically 7%.

They are phenomenal diggers and can shift 540 times their own body weight of earth per day, tunnelling up to 200 meters per day. Since they are rarely longer than 150mm in length, weighing in at between 110-120 grams, this is one mean feat. Moles are industrious hard workers. Typically they work in patterns of approximately 4-hour shift cycles. This means 4 hours working, 4 hours sleeping; all day every day. So, within a 24-hour period, they will work 3 shifts of 4 hours respectively.
