American shrew moles

The smallest species of mole in the world is the American shrew mole, a tiny mammal measuring under 5 centimeters and weighing only about 10 grams.

Found in the U.S. Northwest and Canada's British Columbia, these adorable underground dwellers have smaller front paws than most other moles, a trait that is similar to a shrew.
