An underground burrower is commonly referred to as a MOLE. Moles are small mammals that live in underground tunnels and feed on insects, worms, and other small animals. They have strong claws and powerful front legs that they use to dig their tunnels. They also have poor eyesight, so they rely on their sense of smell and touch to find food. Moles are found in many parts of the world and can be beneficial to gardens and lawns by aerating the soil and eating pests.
